Disproving flat Earth doesn't logically prove round Earth, sure. But that's not how empirical reasoning works. If one model explains a bunch of observations naturally while another needs increasingly elaborate patches, that's evidence in favor of the first model.

There's a difference between "I haven't verified this myself" and "there is no good reason to believe this." You're conflating the two.

But then I've given you a few examples of thought and actual experiments that are very easy to do. That's the opposite of parroting as you can use your own mind to ponder those. But you seem to want to be ignorant, claiming that two theoretical models are equally bad just because you don't want to consider their properties for a second.
