Earth's rotation? Earth does not move.
Gravity? Gravity has never been proven to exist, and even mainstream physicists are questioning its existence as anything independent of electromagnetism. There's a lecture online from an MIT professor of physics who was teaching that gravity is such a weak force that it has no effect on earth, that what we see on earth is due to electromagnetism, and that gravity only works between planets. Except that their cosmological predictions based on gravity are so far off, by orders of magnitude, that they had to invent "dark matter" to account for huge amounts of "missing gravity".
You are delusional.
All you need to do to prove me wrong is go to the edge of the world and take a pic for me (and then jump over the side: If there’s no gravity, you won’t fall).
Any reason you (and any other flat earther) can’t do that???
As for gravity, I prove it every time I drop something.
And for the earth rotating, it is infallibly certain, or I couldn’t hit a one mile shot without factoring in coriolos effect.
