Clues in the international trailer

Hey guys, I just had a thought, if you will indulge me. The first password for projectprometheus.com was of an ancient site in Iraq - 'tell abu shahrain'. Well I looked at the international trailer again at its staring straight at me - Its at about 30 secs into it where you have Holloway talking about the ancient civilisations. Eridu cropped up just before that scene faded out. There were other ancient places mentioned - 'Mesopotamian, Aztec, Cave paintings from France'. The Mesopotamian city we've already figured out. So maybe if we can figure out the most prominent ancient city of the Aztec's, and whatever the name of that French cave is, those place-names might be new passwords for projectprometheus.com and might reveal new content. There seemed to be about 7 or 8 images that Holloway was presenting, each of a different civilisation. So that could be a possible 7 or 8 more passwords. It's just a thought and I may be wrong, but I think that the international trailer holds a few clues...
