I think given what we have learned in the last year or two, I would never say anything is 100% certain. Remember, right is left. Up is down.
Also I recall MegaAnon stating something to the effect that NASA would pretty much implode for spreading lies since the beginning of their existence and something else about the Earth isn’t what we think it is. She said Trump would say “look how long they have lied to you.”
I’m not sure how it all shakes out, but I am keeping an open mind for now.
