They had them, now you try pulling a several ton stone several hundred feet up n the air and holding it there a few days while the next lower stone is dropped into place.

"we don't know how they were built!"

"I know how they would have been built!"
haha...the idea that we could not cut and pile stones into a pyramid shape without modern tech is just so goddamn fucking stupid. I mean, for fuck's sake you delusional goobers, we have literally thousand of years of large, complex stone structures that have appeared since then that were built without modern tech. You guys get in your little tunnel vision modes and seem to forget about the rest of the universe.
