experts in the field have stated that the earth is round ..
Oh man look at this guy appealing to authority. He calls anyone who says the earth is flat a small child with absolutely no first hand knowledge himself.
Dismissal with out investigation is the height of all ignorance.
"What can be asserted without evidence can be dismissed without evidence" - Hitchens's razor is an epistemological razor asserting that the burden of proof regarding the truthfulness of a claim lies with the one who makes the claim, and if this burden is not met, the claim is unfounded, and its opponents need not argue further in order to dismiss it.

The ball earth has no provable evidence. If so show me. The ball earthers are making the claims with no evidence what so ever. Flat earthers are calling you out for proof. There is none. The brainwashed disciples then come out repeating what the holy science book says with no first hand knowledge what so ever. All you can do is spout your book and your fellow brainwashed disciples applaud your intellect.
Water finds it's level. A vacuum needs a container.
That was slick how you tried to turn that argument though and put the proof on flat earth after making fantastic claims of curving water and space travel.
