What makes you think the moon landing was fake?
What makes you think it was not?
1. NASA claims it hasn't been back to the moon because it "lost the technology."
2. Buzz Aldrin's helmet mask reflection shows two light sources "in the sky" that could only be stage lighting.
3. Pictures of Aldrin's suit show he had an impossible wardrobe change "while on the moon."
4. Video footage shot at identical locations claims to have been miles apart and on different days.
5. Apollo 11 LEM pads are seen to be pristinely clear of any lunar dust.
6. Tracks in the completely dry, 250-degree regolith could only have been amorphous due to lack of moisture, but pictures attest to their being as coherent as if they were in earth-based riverbank mud.
7. Apollo craft tech that certainly went into low earth orbit is far more advanced than the tech seen on the LEM in "lunar" pictures.
8. Apollo photos of Earth from what should have been beyond earth orbit show editing artifacts.
9. Apollo photos of Earth from the "lunar surface" show editing artifacts, though they're denied.
10. Video movement of the LEM in "moon orbit" defy reality of phyics.
11. Video of items "on the moon" attest to (an impossible if lunar) atmospheric wind.
12. Video of lunar walks attest to wires being attached to the space suits.
13. Space suit technology was inadequate to lunar walks, 250-degree heat ejection, through induction, convection, glove technology.
14. Various photo editing (e.g., missing buggy tracks)
15. Lack of radiation shielding for the crew
16. Crew attestation to not having any radiation effects through the Van Allen Belts.
17. Stanley Kubrick's involvement
18. Astronauts' radio voices easily being heard over internal rumble of LEM descent engine
19. Artificial lighting evidence in photos and improbably nearly consistent "perfect framing."
... and that's just a sampling. There's copious evidentiary support behind all these claims.
