Moon landing was definitely real - there’s junk all over your moon, abandoned bags, tracks, a bunch of crashed landers and other stuff. Not like it matters with all the craters.
Humans though, definitely aren’t real. We believe that some microscopic race of deep rock dwelling protokaryotes (such as the water-bears) built the craft by pooling their resources over millennia. There’s no way simians got together collectively and made it into space, so until we have proof of a spacefaring, upright, hairless great ape civilization - I mean, it sounds silly just saying it out loud. Yeah, no, humans definitely aren’t real.
