We also have a lot of evidence that snakes can’t speak, people can’t turn plain water into wine, walk on the water and so on.

If I am remembering my stories correctly the snake wasn't a normal snake but more of a representation of Satan. And I think god turned the water into wine and walked on water. We aren't talking about an average person. Neither Satan nor God is around to let us do some experiments on.

Claiming something which can neither be proven or disproven is what constitutes a pseudoscience. By that logic I could claim that we are in fact giant pink elefants hopping around on the moon, while imagining our reality as we currently think to perceive it. Since you can’t disprove that, I must be right. Or am I not?

Yeah fair enough but my point still stands that comparison between god and flat earth is still a bad comparison. Considering the Earth is here right now, and we can experiment on it.
