I still don't get why you and the other guy think pointing out that "Mesopotamians did it first" is relevant. Even if they did and even if the Greeks were extremely influenced by them, their concept of a geometrical zero was still radically different to the Mesopotamians notion, so it is totally irrelevant who was first. The only counter argument could be that they had the same notion, which the Greeks adopted from the Mesopotamians as a complete package.
I don't think this is really complicated. If their understanding was radically different, then the concept couldn't have just "moved over", so disprove my thesis he discussion on "who was first", is obviously irrelevant.

Well, the genuine curiosity and willingness to discuss the subject embodied in a single sentence dismissing my post because of an obviously true statement made me very glad to elaborate and discuss further.
