That's fine. I don't know the exact details of all those disciplines, I like history, but my knowledge of it is limited. I was within reasonable orders of magnitude of the real dates, or lower, which helps my argument that software engineering is incredibly young, which is the whole point :)

The earliest known megalithic construction site is 11 thousand years old: http://en.wikipedia.org/wiki/G%C3%B6bekli_Tepe

The problem is that there has been no continuous architectural tradition. Most of the advanced Roman building methods were completely lost around the 5th century (concrete was not rediscovered until the 18th century). The Egyptians around the time of Cleopatra had no idea about the construction techniques used to build the Great Pyramid of Giza (this is why the Greeks assumed the pyramids were built by slave laborers). This is not surprising considering that Cleopatra lived closer to the first moon landing than she did to the construction of that pyramid.

At the smaller scale. There is a continuous tradition in home construction over that time period. Further, Japan for example had an independent tradition unaffected by Rome's rise and fall.
