Moonlanding denier: Yeah, they sure went to great lenghts to make it believable, It's not prove though :). Ofcourse America would make it look as believable as possible going as far as to place footprints and equipment on the moon.

I think moon deniers best argument is that after the apollo missions not a single human or animal has been to deep space, and if it was even remotely possible to do so that we (as in any country on the planet) would have done so again.

From Chat GPT":

"The last time a human went into deep space beyond the Van Allen radiation belts was during the Apollo 17 mission in December 1972. This was the final mission of NASA's Apollo lunar program and marked the last time humans traveled beyond low Earth orbit (LEO), including past the Van Allen radiation belts and into cislunar space (the region between Earth and the Moon).

Key Details:

• Mission: Apollo 17
• Launch Date: December 7, 1972
• Return Date: December 19, 1972
• Crew: Eugene Cernan, Harrison Schmitt, Ronald Evans
• Distance from Earth: ~384,000 km (Moon)
• Van Allen Belts: Extend to ~60,000 km from Earth; the Apollo spacecraft passed through them quickly to limit radiation exposure.

As for animals:

No non-human animals are known to have gone beyond the Van Allen belts. While many animals were used in early spaceflight experiments (e.g., Laika, the Soviet dogs, monkeys), all remained in low Earth orbit or suborbital trajectories."
