Nothing would destroy my faith.
I'm talking about your faith in a flat earth.
If you were to accept the moon landings as genuine, you'd have to accept the photos, pieces of moon rock, eye witness accounts and interviews as genuine. (This is called evidence.)
If you accepted a photo of the earth, taken from space, as genuine, that would destroy your belief that the earth is flat and not a globe. It's clear from the photos we have that the earth is a globe. Never mind science or calculations etc. - we can see that it is.
Obviously you're not going to accept that - your faith, and I don't mean Christian faith - is that we all live on a flat, CD shaped planet; sorry, wandering star.
So you have no choice but to discredit the astronauts, scientists, claim that all evidence is faked and everyone is lying.
Us flat earthers do not have the resources or the money that NASA has.
Because NASA is a huge organisation; properly set up, accredited, organised and funded, which works on space exploration, moon landings and research and so on.
They have educated, and reputable, people working for them - including a scientist whose YouTube video you chose to post.
All the flat-earthers have is a bunch of people saying "yeah, it's all fake."
That's what people have done with the flat earth lie - "keep repeating it; someone will believe it".
