Quote - All they know thus far is that the pyramids were built using higher math skills and aligned with certain constallations. Heck, we can't even figure out how they went about building something that massive in size with the technology and tools that they had back then.

Yeah, actually we can.  The only debates (which may never be solved) are which of several methods may have been used, the main one being the style of ramp used at the Giza pyramids.  Everything else (cutting and dressing the stones, moving them, placing them) have all been replicated using tools and materials available at the time.

You'll see statements that "We couldn't do it today!"  What that means is that economically we couldn't do it today.  Given a few thousand workers manually hauling stone blocks working for only their meals and a place to sleep for two decades?  Sure, it could be done today.  Given an unlimited budget and modern equipment?  Done even faster.
