That's fair enough...but as you say, there's no conclusive proof is there.
There is never conclusive proof when it comes to science. Nothing is ever proven.
TIt's easy for all of us to sit here and say this and that in a belief that we actually know what we are all talking about as in the "reality" of what "is" in the world or what the world is...but we are all clutching at straws and making best guesses, yet some believe they aren't because they have been have been indoctrinated to the point of saturation, where anything written in books and said by a nominated in your face professor, is the right answer.
We are far beyond making best guesses about the shape of our world. Take just the foucault pendulum experiment -
It can be proven Mathematically that a swinging pendulum on a non-rotating flat plane will continue to swing in one direction indefinitely, while on a rotating globe it will rotate at a speed and direction based on a simple formula that is dependent on your latitude of where the experiment is conducted.
So the experiment is performed, and we find that the pendulum does in fact rotate. So we can now conclude that the non-rotating flat plane cannot possibly be the correct shape of our Earth. It might be a spherical Earth or even a rotating flat plane. But we also know that if a flat plane was rotating, then we'd feel the same effects as that of objects on a carousel; they will fly outwards from the centre of the carousel. Since this doesn't happen either, we can safely conclude that out of our options given, the round Earth is the most sensible answer.
And that is just one experiment. There are many more that also support a round Earth and completely debunk the flat Earth. Just because you refuse to acknowledge and often don't even understand what the results tell us, doesn't mean the conclusions made are incorrect.
I'd say channel your energies into a more critical thought and try and smash the round rotating earth indoctrination and see if the flat earth can be added to.
You mean, ignore everything I know about science and start again - but this time I should believe that everything in science is wrong, and I need to find alternate theories to everything, even if they don't add up?
Why?
Because the rotating round earth has nothing to test your mind if you follow what's been infused into you all your life but a flat earth has many more avenues to go down and many more pieces to fit together and the more people that attempt to do it, the more chance it will all fit.
You want to test your mind? LOL go learn some science.
