Facts don’t require any establishment. They are facts. Earth is spherical.

You do yourself a disservice by contradicting yourself immediately. The Earth historically was always seen as the center of the universe and not seen as a sphere at all, many cultures thought it was flat and that you could "sail out too far and fall off the edge of the earth". The fact that the earth is sphereical WAS ESTABSLISHED through deduction, reasoning, and science. It is an established fact that the earth is sphereical.

It is a fact that this post is an over rewarded rant. That’s it. That’s all that I said. There is nothing more to add.

You may not like the facts that are presented here because it goes against your personal beliefs, but that's irrelevant. Facts are facts, and this article does provide facts. Handwaving away facts doesn't make them untrue.
