Skara Brae was occupied as early as 3180 BC. Egyptians didn't finish the first pyramids until ~2600 BC.

It is truly a wonder - especially given the different circumstances than a fertile river valley.

Of course 2600 BCE is about half way between the early Pre-dynastic period and the end of the Ptolemeic period. And only about a third of the way to present day.

Egypt is mind bogglingly long lived.

I don't think you really need to compare / remember that... we're talking history here, not some sort of building scorecard.

Different kinds of buildings though - I've been into one of the pyramids at Ghiza (Khafre's) and it actually doesn't look that interesting. I find the buildings at Skara Brae interesting because they are more human scale (beds and other furniture) and were where people actually lived for many hundreds of years - quite a bit before the pyramids at Giza at least.
