I agree some conspiracy theories are utterly bonkers
This is one of them.
You have asked people to prove the landings happened. You have been shown photographs and eyewitness testimony, including from someone on these forums who father-in-law worked on the Apollo rocket. (Forgive me if that is not quite right.)
Your answer is/has been "fake, lies".
You have been told that NASA planned and carried out the space missions.
Your answer has been that NASA are ALL liars.
You don't know why they would have been faked or why anyone would have spent billions of dollars to convince us that something which is not important was true. Your only answer is that it "must be", and the Christian astronauts "must be lying". Why? Because the moon landings destroy your belief that the earth is not a globe.
Anyone who sees a photo of the earth taken from the moon/rocket can SEE that it is a globe - the beautiful globe that God created. But no, it's easier to shout "CGI" (which they didn't have in those days) and continue with your "the earth is a flat, 40,000 foot deep shape, with 4 corners and enclosed by the Antarctic."
This, of course, is completely unscientific - but then you know zilch about science, so it's not surprising.
