Well I'll quote the arguments that

The Top 15 Reasons Why No Man Has Ever Set Foot on the Moon
15. "Tricky Dick" Richard Nixon was president at the time. He was the king of cover-up, secret tapes and scandal. Think about all of his potential antics that were not discovered.
14. A successful manned mission to the moon offered a wonderful pride-boosting distraction for the near revolt of the US citizens over 50,000 deaths in the Vietnam War.
13. The Soviets had a five-to-one superiority to the U.S. in manned hours in space. They were first in achieving the following seven important milestones:
First manmade satellite in earth orbit
First man in space
First man to orbit the earth
First woman in space
The first crew of three astronauts onboard one spacecraft
The first space walk
The first of two orbiting space craft rendezvousing
This put America at a perceived military disadvantage in missile technology during the very height of the Cold War.
12. Neil Armstrong, the first man to supposedly walk on the moon, refuses to give interviews to anyone on the subject. "Ask me no questions, and I'll tell you no lies." Collins also refuses to be interviewed. Aldrin, who granted an interview, threatened to sue us if we showed it to anyone. See streaming video: "Buzz says, "Buzz Off!"
11. Newly retouched photographs correct errors from previously released versions. Why would they be updating thirty-year-old pictures if they really went to the moon?

10. Rediscovered lost footage shows the American flag blowing in the wind. The wind was probably caused by intense air-conditioning used to cool the astronauts in their lightened, uncirculated, space suits. The cooling systems in the backpacks would have been removed to lighten the load not designed for earth's six times heavier gravity, otherwise they might have fallen over. See streaming video: "Flag blowing in the wind."
9. Enlarged photographs underneath the lunar lander's 10,000 lb. thrust engine show the soil completely undisturbed. During ground tests there was grave concern for the vehicle falling into the hole the engine created as it descended. An oversight that they would have to keep consistent for all subsequent moon missions. They attributed it to the effect of no atmosphere (except for the flag blowing in the wind - see # 10!)
8. Rare, uncirculated photographs, allegedly from the moon's surface, show scenes supposedly lit solely by sunlight. Yet they contain shadows that do not run parallel with each other, indicating supplemental artificial light. Sunlight would cast shadows that would never intersect. See our streaming video: "Photographic Analysis" for some eye opening examples.
7. The moon is 250,000 miles away. The space shuttle has never gone more than 400 miles from the Earth. Except for Apollo astronauts, no humans even claim to have gone beyond low-earth orbit. When the space shuttle astronauts did get to an altitude of 400 miles, the radiation of the Van Allen belts forced them to a lower altitude. The Van Allen radiation belts exist because the Earth's magnetic field traps the solar wind. See streaming video: "Radiation Belts."
6. The top portion of the lunar module which landed on the moon supposedly popped up off the moon with two astronauts aboard, entered lunar orbit 60 miles up, and docked with the command module in lunar orbit. To look at its design and think such could have actually occurred is absolutely ludicrous. The fuel tanks were nowhere near one-sixth the size of those on the space shuttle as one would expect to achieve lunar orbit.
5. The surface of the moon is a vacuum. The landing module would have been heated to 250 degrees on the light side where they landed. There is no way they could have rejected the heat for as long as 72 hours as they claim on some Apollo missions. How long do you think you could keep your car cool on a hot day running off battery power?
4. Take a look at the lunar module which supposedly flew from lunar orbit to the surface of the moon. It is a cylindrical shape with a high center of gravity and one big thrust engine at the bottom. Upon just looking at this design, to think it would not immediately pinwheel and crash, as the lunar module trainer did three weeks prior on Earth, is absurd.
3. After the Apollo 11 mission, Armstrong, Collins and Aldrin gave a press conference. When asked whether they remembered seeing any stars from the surface of the moon, Collins, who was supposedly in the command module the whole time, gave a wrong answer to a question he should not have been answering. The relevant portion of this clip is in my documentary; viewing it with an understanding of the circumstances makes it clear they were lying about having traveled to the moon. I'm saying Collins blew it right then and there and I honestly cannot understand why there is even further discussion on the whole topic. Furthermore, if you obtain a written transcript of the press conference you'll see that the comment is erroneously attributed to Aldrin. Honest mistake or cover-up?
2. In 1967 three astronauts were burned alive on the launch pad. The upshot of the congressional inquiry was that the entire Apollo program was in shambles and it was a miracle no one was killed sooner. All of the problems were supposedly fixed by 1969, just two years later. How could they have made such a large improvement in "quality control" in such a short period of time.
1. All Apollo missions stayed in low-earth orbit for the duration of the trip. We uncovered some mislabeled, unedited, behind-the-scenes footage from NASA that shows the crew of Apollo 11 clearly staging a shot of being half-way to the moon. This clip, shown in our documentary, proves they did not leave low-earth orbit. You won't see this anywhere else!
Some people just like conspiracy theories no matter how stupid they are.
