As an aside...I am fully persuaded that we have indeed been to space. I reckon I will remain so until verifiable evidence is presented otherwise.
There will never be verifiable evidence to the contrary, we humans have been to space, we've been to the moon, there are heaps of verifiable evidence to support this, phot and video recordings documenting everything, samples, vehicles, eye witnesses...
It's one thing though to question something like the moon landing, after all that's quite a feat, but once evidence is presented to prove this indeed happened it can be put to rest...
These flat earthers go above and beyond, I cannot even grasp a fraction of their understanding and reasoning behind this belief...
