Who specifically invented terrace farming?

Question

I know the Incas did, but who was the actual guy.

Answer 1

that would thoc cxul, an Incan Gad about and inventor. Rumor has it his quipus were the best (if you know what I mean...)

Answer 2

Considering that the Chinese, Mesopotamians and Babylonians were doing it 2,000 years ago, I suspect it will be pretty hard to find the actual guy's name.
