How did he see all the Kingdoms of the earth from the top of a high mountain then? Are the words of the Bible not good enough for you to draw a reasonable conclusion, that the earth must be flat?

Citation please. And don't bother with the Isaiah claim. The word used in Isaiah translates to circle (the ancient belief that the world was a disc was common). The writer had words available that would have translated to the modern "sphere", or "ball" and didn't use them.
Elsewhere the sky is referred to as a vault, writers speak of the stars "falling to earth", there are reference to the corners of the earth, and its foundations. There is no sense in the Bible of the scale of the world, or even that any wider world outside a small corner of the Middle east exists at all. No sense of the scale of the universe. We shouldn't be surprised. The book was written by people who didn't know of these things, and God apparently didn't bother to educate them in such matters.
