1: Lots of people say "Oh that's a fish eye lenses" to debunk the curve of the Earth, but Fisheye lenses can make flat things look round, and make round things look flat, so you have no proof either way.
It's not used to debunk the curve, just debunk the evidence of the curve. It's not meant to be proof either way.
but you forget that it is not debunked.
as you said, fisheye does not prove it either way, therefor it does not disprove it either way.
2: Ever realize why we switched away from the flat earth model? In science we go with what we think is right for the time based on calculations. We did not have the tools in the past to measure the curve properly, so we thought it was flat, since we got the new technology we experimented, measured, tested, and found the earth was round!
This isn't really a question that can be answered. If you want people to engage then give instances of new technology, new measurements, and why it proves RET.
the global earth is proven many time because science developed more accurate methods to examine problems.
3: For those who say the ISS videos were fake, how can you fake 0g environments?
Movies manage it.
I say that movie is not able to fake all the video that are made from outer space.
if you say I am wrong, prove it
4: Many people say we never made it to space, got any proof? You can say the same to space, but if we did not make it, what about the Hubble pictures? Hm?
What makes Hubble pictures inherently accurate? Images have been faked for pretty much as long as humans have had photography.
I am a Round Earther, just to note.
Same here, but if you want to ask meaningful questions you have to give your reasoning as to why you see them as issues.
so you believe that the earth is a globe, but why?
you question all the evidence for a global earth but you still believe that the earth is a globe.
what are the evidence that you believe in a global earth and not in a flat earth?
