The most commonly accepted explanation of this is that the space agencies of the world are involved in a conspiracy faking space travel and exploration. This likely began during the Cold War's 'Space Race', in which the USSR and USA were obsessed with beating each other into space to the point that each faked their accomplishments in an attempt to keep pace with the other's supposed achievements. Since the end of the Cold War, however, the conspiracy is most likely motivated by greed rather than political gains, and using only some of their funding to continue to fake space travel saves a lot of money to embezzle for themselves.

On February 24th, YouTubers GlobeBusters (featured in the documentary) uploaded a video entitled "Behind The Curve Documentary Reveals Globe Earth Desperation!" The video explains that the documentary was misleading. It gained 41,000 views in a couple weeks (shown below, left). On February 25th, Jeranism (also featured in the documentary) responded negatively to the film (shown below, right).
70.) Mr. Lockyer, in describing his picture of the supposed proof of the Earth's rotundity by means of ships rounding a "hill of water," uses these words: – "Diagram showing how, when we suppose the earth is round, we explain how it is that ships at sea appear as they do." This is utterly unworthy of the name of Science! A science that begins by supposing, and ends by explaining the supposition, is, from beginning to end, a mere farce. The men who can do nothing better than amuse themselves in this way must be denounced as dreamers only, and their leading dogma a delusion. This is a proof that Earth, not a globe.
95) On a clear day from the highland near Douglas Harbor on the Isle of Man, the whole length of the coast of North Wales is often plainly visible to the naked eye. From the Point of Ayr at the mouth of the River Dee to Holyhead comprises a 50 mile stretch which has also been repeatedly found to be perfectly horizontal. If the Earth actually had curvature of 8 inches per mile squared, as NASA and modern astronomy claim, the 50 mile length of Welsh coast seen along the horizon in Liverpool Bay would have to decline from the center-point an easily detectable 416 feet on each side! 

21.) Man's experience tells him that he is not constructed like the flies that can live said move upon the ceiling of a room with as much safety as on the floor: – and since the modern theory of a planetary earth necessitates a crowd of theories to keep company with it, and one of them is that men are really bound to. the earth by a force which fastens them to it "like needles round a spherical loadstone," a theory perfectly outrageous and opposed to all human experience, it follows that, unless we can trample upon common sense ane ignore the teachings of experience, we have an evident proof that the Earth is not a globe.
 197) Some people claim there is no motive for such a grand-scale deception and that flat or a ball makes no difference. By removing Earth from the motionless center of the Universe, these Masons have moved us physically and metaphysically from a place of supreme importance to one of complete nihilistic indifference. If the Earth is the center of the Universe, then the ideas of God, creation, and a purpose for human existence are resplendent. But if the Earth is just one of billions of planets revolving around billions of stars in billions of galaxies, then the ideas of God, creation, and a specific purpose for Earth and human existence become highly implausible. By surreptitiously indoctrinating us into their scientific materialist Sun-worship, not only do we lose faith in anything beyond the material, we gain absolute faith in materiality, superficiality, status, selfishness, hedonism and consumerism. If there is no God, and everyone is just an accident, then all that really matters is me, me, me. They have turned Madonna, the Mother of God, into a material girl living in a material world. Their rich, powerful corporations with slick Sun-cult logos sell us idols to worship, slowly taking over the world while we tacitly believe their “science,” vote for their politicians, buy their products, listen to their music, and watch their movies, sacrificing our souls at the altar of materialism. To quote Morris Kline, “The heliocentric theory, by putting the sun at the center of the universe ... made man appear to be just one of a possible host of wanderers drifting through a cold sky. It seemed less likely that he was born to live gloriously and to attain paradise upon his death. Less likely, too, was it that he was the object of God’s ministrations.”
164) Analysis of many interior videos from the “International Space Station,” have shown the use of camera-tricks such as green-screens, harnesses and even wildly permed hair to achieve a zero-gravity type effect. Footage of astronauts seemingly floating in the zero-gravity of their “space station” is indistinguishable from “vomit comet” Zero-G airplane footage. By flying parabolic maneuvers this Zero-G floating effect can be achieved over and over again then edited together. For longer uncut shots, NASA has been caught using simple wires and green screen technology.

72.) Astronomers tell us that, in consequence of the Earth's "rotundity," the perpendicular walls of buildings are, nowhere, parallel, and that even the walls of houses on opposite sides of a street are not! But, since all observation fails to find any evidence of this want of parallelism which theory demands, the idea must be renounced as being absurd and in opposition to all well-known facts. This is a proof that the Earth is not a globe.
In Mr. Proctor's "Lessons in Astronomy," page 15, a ship is represented as sailing away from the observer, and it is given in five positions or distances away on its journey. Now, in its first position, its mast appears above the horizon, and, consequently, higher than the observer's line of vision. But, in its second and third positions, representing the ship as further and further away, it is drawn higher and still higher up above the line of the horizon! Now, it is utterly impossible for a ship to sail away from an observer, under the, conditions indicated, and to appear as given in the picture. Consequently, the picture is a misrepresentation, a fraud, and a disgrace. A ship starting to sail away from an observer with her masts above his line of sight would appear, indisputably, to go down and still lower down towards the horizon line, and could not possibly appear - to anyone with his vision undistorted - as going in any other direction, curved or straight. Since, then the design of the astronomer-artist is to show the Earth to be a globe, and the points in the picture, which would only prove the Earth to be cylindrical if true, are NOT true, it follows that the astronomer-artist fails to prove, pictorially, either that the Earth is a globe or a cylinder, and that we have, therefore, a reasonable proof that the Earth is not. a globe.
34.) If the Earth were a globe, there certainly would be – if we could imagine the thing to be peopled all round – "antipodes:" "people who," says the dictionary, "living exactly on the opposite side of the globe to ourselves, have their feet opposite to ours: – people who are hanging heads downwards whilst we are standing heads up! But, since the theory allows us to travel to those parts of the Earth where the people are said to be heads downwards, and still to fancy ourselves to be heads upwards and our friends whom we have left behind – us to be heads downwards, it follows that the whole thing is a myth – a dream – a delusion – and a snare; and, instead of there being any evidence at all in this direction to substantiate the popular theory, it is a plain proof that the Earth is not a globe.

Astronomers are in the habit of considering two points on the Earth's surface, without, it seems, any limit as to the distance that lies between them, as being on a level, and the intervening section, even though it be an ocean, as a vast "hill"-of water!" The Atlantic ocean, in taking this view of the matter, would form a "hill of water" more than a hundred miles high! The idea is simply monstrous, and could only be entertained by scientists whose whole business is made up of materials of the same description: and it certainly requires no argument to deduce, from such "science" as this, a satisfactory proof that the Earth is not a globe.

196) Quoting Marshall Hall, “In short, the sun, moon, and stars are actually doing precisely what everyone throughout all history has seen them do. We do not believe what our eyes tell us because we have been taught a counterfeit system which demands that we believe what has never been confirmed by observation or experiment. That counterfeit system demands that the Earth rotate on an 'axis' every 24 hours at a speed of over 1000 MPH at the equator. No one has ever, ever, ever seen or felt such movement (nor seen or felt the 67,000MPH speed of the Earth's alleged orbit around the sun or its 500,000 MPH alleged speed around a galaxy or its retreat from an alleged 'Big Bang' at over 670,000,000 MPH!). Remember, no experiment has ever shown the earth to be moving. Add to that the fact that the alleged rotational speed we've all been taught as scientific fact MUST decrease every inch or mile one goes north or south of the equator, and it becomes readily apparent that such things as accurate aerial bombing in WWII (down a chimney from 25,000 feet with a plane going any direction at high speed) would have been impossible if calculated on an earth moving below at several hundred MPH and changing constantly with the latitude."
On November 12, 2016, I had the opportunity to conduct this experiment. I was near the water’s edge, just beyond the surf, at Virginia Beach from middle to late afternoon. When I began, the air temperature was 50 degrees F, and the temperature dropped a degree or two by the time that I was done, near sunset. The water temperature was 62–64 degrees F, so the air immediately above the water was at least ten degrees warmer than the air temperature a short distance above the water. I photographed two cargo ships as they made their way out to sea from the port at Hampton Roads. I mounted a digital SLR camera on a 3.5-inch Questar telescope, having a 1,200-mm focal length. The ISO setting on the camera was 100 for all photographs.
Then scriptures say at 1 John 5:19 that "the whole world is lying in the power of the Wicked One". The people who are ultimately responsible for this deception, the NWO folks, Free Masons, and illuminati are being controlled by SATAN and his demons, to "blind the minds" of us. This deception started with the "mysteries" before Babylonian times during the times of Chaldeans and descendants of Nimrod. No human could have continued this deception for so many CENTURIES. Only a being like one who has been in existence since before the earth was. is plenty more I would like to share with the flat earthers. It all is in complete agreement with what Eric has shared, which, has actually validated my beliefs per se. I am total agreement with you guys about NASA. I am a retired space shuttle engineer. I always knew they couldn"t escape the "Van Allen" belts, but only until a little less than a myear ago did I understand what a firmament was. Eric you are great!!!
37.) If the Earth were a globe, there would, very likely, be (for nobody knows) six months day and six months night at the arctic and antarctic regions, as astronomers dare to assert there is: – for their theory demands it! But, as this fact – the six months day and six months night – is; nowhere found but in the arctic regions, it agrees perfectly with everything else that we know about the Earth as a plane, and, whilst it overthrows the "accepted theory," it furnishes a striking proof that Earth is not a globe.
123) Heliocentrists’ astronomical figures always sound perfectly precise, but they have historically been notorious for regularly and drastically changing them to suit their various models. For instance, in his time Copernicus calculated the Sun’s distance from Earth to be 3,391,200 miles. The next century Johannes Kepler decided it was actually 12,376,800 miles away. Issac Newton once said, “It matters not whether we reckon it 28 or 54 million miles distant for either would do just as well!” How scientific!? Benjamin Martin calculated between 81 and 82 million miles, Thomas Dilworth claimed 93,726,900 miles, John Hind stated positively 95,298,260 miles, Benjamin Gould said more than 96 million miles, and Christian Mayer thought it was more than 104 million! Flat-Earthers throughout the ages, conversely, have used sextants and plane trigonometry to make such calculations and found the Sun and Moon both to be only about 32 miles in diameter and less than a few thousand miles from Earth.
96) From “100 Proofs the Earth is Not a Globe” by William Carpenter, “If we take a journey down the Chesapeake Bay, by night, we shall see the ‘light’ exhibited at Sharpe's Island for an hour before the steamer gets to it. We may take up a position on the deck so that the rail of the vessel's side will be in a line with the ‘light’ and in the line of sight; and we shall find that in the whole journey the light won't vary in the slightest degree in its apparent elevation. But, say that a distance of thirteen miles has been traversed, the astronomers' theory of ‘curvature’ demands a difference (one way or the other!) in the apparent elevation of the light, of 112 feet 8 inches! Since, however, there is not a difference of 100 hair's breadths, we have a plain proof that the water of the Chesapeake Bay is not curved, which is a proof that the Earth is not a globe.”
A "Standing Order" exists in the English Houses of Parliament that in the cutting of canals, &c., the datum line employed shall be a "horizontal line, which shall be the same throughout the whole length of the work." Now if the Earth were a globe, this "Order" could not be carried out: but, it is carried out: therefore it is a proof that the Earth is not a globe.

If the Earth were a globe, there certainly would be - if we could imagine the thing to be peopled all round - "antipodes:" "people who," says the dictionary, "living exactly on the opposite side of the globe to ourselves, have their feet opposite to ours: - people who are hanging heads downwards whilst we are standing heads up! But, since the theory allows us to travel to those parts of the Earth where the people are said to be heads downwards, and still to fancy ourselves to be heads upwards and our friends whom we have left behind - us to be heads downwards, it follows that the whole thing is a myth - a dream - a delusion - and a snare; and, instead of there being any evidence at all in this direction to substantiate the popular theory, it is a plain proof that the Earth is not a globe.
I started reading this e-book today and finished it today. Great Work ! I have to say, even if approached flat-earth model fistly 3 month ago, this Book really opened my eyes completely and still i know how strong the Brainwash is and even if you - by ratio - see something clear, it will still need a time to be completely internalized. Thx alot, greetingz from Germany also i was able to watch the video below, which oc is blocked in Germany, but this led me to HotSpotShield, also very important for a native German, greetingz from Frankfurt/Germany, Benjamin

Satan is programming the world to believe in everything that is opposite of the Bible. In the Globe earth model the sun is the center of the Universe, but the Bible never refers to the earth moving around the sun. The Bible says instead, that the earth is stable, on a firm foundation, and cannot be moved (1 Chronicle 16:30; Psalm 93:1; Psalm104:5).
79.) The remark is common enough that we can see the circle of the Earth if we cross the ocean, and that this proves it to be round. Now, if we tie a donkey to a stake on a level common, and he eats the grass all around him, it is only a circular disc that he has to do with, not a spherical mass. Since, then, circular discs may be seen anywhere – as well from a balloon in the air as from the deck of a ship, or from the standpoint of the donkey, it is a proof that the surface of the Earth is a plane surface, and, therefore, a proof that the Earth is not a globe.
41) Similar calculations made from the Cape of Good Hope, South Africa to Melbourne, Australia at an average latitude of 35.5 degrees South, have given an approximate figure of over 25,000 miles, which is again equal to or greater than the Earth’s supposed greatest circumference at the equator. Calculations from Sydney, Australia to Wellington, New Zealand at an average of 37.5 degrees South have given an approximate circumference of 25,500 miles, greater still! According to the ball-Earth theory, the circumference of the Earth at 37.5 degrees Southern latitude should be only 19,757 statute miles, almost six thousand miles less than such practical measurements.
Well I dont rule out a creator because so many things were by design. Look at how some animals protect themselves. Take a skunk, that is ingenious, but doubt it was through evolution. Look at a raccoon, cool looking mast dont you think, that's what Hollywood says as well. Look a all males, their penis retracts when not in use, hmm somebody was thinking. No, not evolution but careful breeding by some one. Probably many Somebodies came here and created their own species, that's why we look a little different from continent to continent. who knows how far back it goes, maybe all mammals were created by somebody. But then whales might be smarter than us.
110) Magellan and others’ East/West circumnavigations of Earth are often quoted as proof of the ball model. In actual fact, however, sailing or flying at rights angles to the North pole and eventually returning to one’s original location is no more difficult or mysterious than doing so on a globe. Just as an architect’s compass can place its center-point on a flat piece of paper and trace a circle either way around the “pole,” so can a ship or plane circumnavigate a flat-Earth.
69.) Mr. Lockyer says: "The appearances connected with the rising and setting of the Sun and stars may be due either to our earth being at rest and the Sun and stars traveling round it, or the earth itself turning round, while the Sun and stars are at rest." Now, since true science does not allow of any such beggarly alternatives as these, it is plain that modern theoretical astronomy is not true science, and that its leading dogma is a fallacy. We have, then, a plain proof that the Earth is not a globe.
78.) "Yes, but we can circumnavigate the South easily enough," is often said by those who don't know, The British Ship Challenger recently completed the circuit of the Southern region – indirectly, to be sure – but she was three years about it, and traversed nearly 69,000 miles – a stretch long enough to have taken her six times round on the globular hypothesis. This is a proof that Earth is not a globe.

80) In Chambers’ Journal, February 1895, a sailor near Mauritius in the Indian Ocean reported having seen a vessel which turned out to be an incredible 200 miles away! The incident caused much heated debate in nautical circles at the time, gaining further confirmation in Aden, Yemen where another witness reported seeing a missing Bombay steamer from 200 miles away. He correctly stated the precise appearance, location and direction of the steamer all later corroborated and confirmed correct by those onboard. Such sightings are absolutely inexplicable if the Earth were actually a ball 25,000 miles around, as ships 200 miles distant would have to fall approximately 5 miles below line of sight!
29. If the Earth were a globe, it would, unquestionably, have the same general characteristics - no matter its size - as a small globe that may be stood upon the table. As the small globe has top, bottom, and sides, so must also the large one - no matter how large it be. But, as the Earth, which is "supposed" to be a large globe, bas no sides or bottom as the small globe has, the conclusion is irresistible that it is a proof that the Earth is not a globe.
25.) The surveyor's plans in relation to the laying of the first Atlantic Telegraph cable, show that in 1665 miles – from Valentia, Ireland, to St . John's, Newfoundland – the surface of the Atlantic Ocean is a LEVEL surface – not the astronomers' "level," either! The authoritative drawings, published at the time, are a standing evidence of the fact, and form a practical proof that Earth is not a globe.
