Well, I've done some more reading. Looks like the Hellinikon is the oldest with Caral being the second oldest but, I think we're talking about 100 years difference in age of the two. I expect this is within the +- range of radiocarbon dating.
So, we have Greece, Peru then Egypt in that order with the oldest pyramids...something most would not expect.
"The Cuicuilco Pyramid in Mexico is another enigma. It was geologically dated to before 8,500 BC based upon the fact that it existed before the first volcanic eruption of Mount Xitli."
