Agreed. Flat earther begin with an assertion. The Earth is flat. Next they assert whatever is necessary to make whatever we experience and witness around us fit in with that first assertion. Re-inventing the laws of physics along the way in whatever way is necessary to suit their cause. Any and all evidence that suggests they are wrong they say has been hoaxed, faked or whatever.
The flat earth movement often say they are in 'search for the truth'. Is that the truth as it actually is or the truth as you want it to be?
There is no evidence to say they are wrong.
There is no evidence to say what you follow, is right.
There's circumstantial evidence for all sides but not a lot of closer proof.
You mention re-inventing the laws of physics.
What are the laws of physics?
What are these laws that supposedly show and speak a truth for what you abide by?
You're reliant, or made to be reliant on names of yesteryear/century as if those people knew all the answers and today we simply follow them because they got it supposedly right, even though they had little to go on.
There's a lot of physical reality out there that shows the world to be much different to the one we're told/bullied into accepting.
The problem is, those at the top have all the ready made answers at hand, no matter how magical those answers are...and people simply accept them because they're told and sold to them by people with conjured scientific badges on the
theory/hypotheses/musings or fairy tales of whatever is thrown out.
