Does anyone even listen to creationists these days?

The various crop + stock combos need to get from place to place, hence Eurasia being the powerhouse of civilisation. If Eurasia isn't hospitable enough, there is no spread of agriculture.

Agriculture developed independently and at around the same time in Australia, Papua, the Americas and the Far East from what I have read.

That it happened to lead to civilization in the ancient Near East is I believe to do with the requirements of hosting agriculture in such a place. Max Weber says a fair bit about this - building the irrigation canals in Mesopotamia that were necessary for agriculture meant people had to band together under leaders and develop a system of almost slave labour. This process didn't happen in places that could rely on rainfall etc.
