The dates are all wrong. The Central American pyramids were built thousands of years apart from the Egyptian ones.
Then the hypothesis must be tweaked! It was in fact the Americans who sailed to Egypt, saw the pyramids and came back with the know how!

Not quite - the Egyptian pyramids were built first, they were just built too far in advance for it to make any sense whatsoever for them to be built by the same people.

I believe the Egyptian periods were built about the 3rd to the 6th Dynasties (about 2700-2500 BC).
I believe the Mayan pyramids were built during the First Millennium AD--maybe about 600 AD, during the Classic period.
Those dates are consistent with what I remember.
We're biased to view anything from about 10,000BC to 800AD as "a long time ago, either side of Christ but before 1066", but we'll happily acknowledge the changes in human culture between 1945 and 1975.
The "one builder" hypothesis states that Egyptians built some pyramids, sailed to America, and built some more. OK, maybe if we could find some evidence... except they'd have to sit around not building pyramids for 3000 years, then decide to start building again! Utterly ludicrous.
