That depends on your stone and your concrete. Georgian stone (1714-1830 AD). Roman concrete (118–128 AD)

Aliens would have poured concrete.

Yes, they're "overplayed". The pyramids are completely explicable within what is known about Egypt.

the explanations of all that stuff in the book were more interesting than the main spaceship story. I still need to get into the second book though. There's other stuff throughout the world that can only he seen from either from space or flight. So were they talking to imaginary gods or were there "people" up there that they saw flying around?

Ancestors were masters masons. We can't build stone pyramids or anything like it with our modern tech. I think they are pretty worthy of awe.

Other cool things:

Petra's entrance was carved from a single rock face from the top down.

We still don't know how the stones of Puma punku were cut and erected.

"Area 51" by Bob Mayer brings up the pyramids as being becons to "our" home world. I've made mention to that book a few times now as it makes mention of conspiracy stuff with explanations that make sense.

do you think that maybe they prop up the pyramids in hopes that we ignore the more difficult to explain wonders of the world on purpose

why not? there's some pretty cool stuff put there that would require some serious thought amd discussion on how it came to be. Thought provoking stuff seems to have disapeared from tv.

no doubt they have covered up early industrialization and machinery that were used to engineer the roads, pyramids and other features of the ancient world.

if there was a worker/slave every 2 square feet I don't see how it could have been built in a few years, also one fucking mistake and you would see it!

The builders were likely educated and trained in architecture and more like "blue collar" middle class workers than "slaves"

slaves would not be able to do the "laser" precision work but would be much better at the raw manpower to most importantly provide food and deliver raw materials to the artisans.

Careful what you're thinking... You don't want have to commit suicide! Anyhow, interesting point. Do you have any other examples beyond the Elloea?
