I will apologize for sounding dismissive, I do not mean to come across as such; more that, I have not yet accepted any of the beliefs put forth yet.

I state they are beliefs because when you are a proponent of a construct in a way that voices acceptance and cannot produce meaningful evidence to the statement it is simply a belief.

If I was to say "there is a god" clearly I could not prove such a thing, so it is just a claim revealing a belief.

If I was to say "this rock is hard" we can easily examine the rock and compare its hardness properties to a variety of other objects and objectively concur and agree on some parameters. What this does is produce 'rock' hard evidence to the claim removing belief and replacing it with accepted explanation.

For me, this would be the goal of any activity regarding a claim that there is any value in stating the earth is flat.

Firstly, it is a crazy topic because it makes no physical sense, it is founded long ago, back when humans were easily manipulated into any form of belief.

Secondly, the claim that we understand enough to prove one way or the other without significant effort and tooling is simple minded. If we could easily prove it, we would have the evidence.
