Pyramids do not
need (require) UFOs or whatever to build them
they do take a great deal of time, effort and brains.
Could the techniques have been learned/discovered form some previous civilization...yes, that's possible but not absolutely required.
I takes time but we slowly learn the *rational* facts behind much of the mysteries the ancient world has left us.
It's fun though to have mysteries, but not good to become dogmatic in thinking on them.
The truth of the matter is *not known*, so no one has the right to be dogmatic!
Could the Pyramids have been built with the help of aliens...likr it or not, I have to say yes,
because we have no independant observers there at the time, which is the ONLY way to be 100% sure
but we don't have any evidence of "aliens" being there or their absolutely required necessity to construct such, so such esoteric suggestions are not likely to be correct.
Science is probability, which is about by using rational logic based on best evidence, and evidence can CHANGE over time as more is uncovered.
So the odds of "aliens/magic/weird" being involved in the Pyramids is VERY small.
But it cannot be ruled out unless we had say, a time machine to observe for ourselves.
But that applies to
everything, every damn thing that is not carefully observed and recorded throughout history could have an infinite number of possible explanations!
Usally the explanations are simple, sometimes though it's more ocmplex, and a very few we as yet have no answers for
that is the great dilemma and bugbear of Science: there is no certainty, which is a pain in the ass
and made much worse by fraud, abuse etc (such as say, the lies for profit of many pharmaceutical trials)
Science requires absolute confidence in its data amd that such data is constantly,
constantly updated and re-checked in light of further information.

now theres' a grand mystery, even though we've uncovered much of what it does , we still don't know the evolution of the item and background
what thoughts/people/cuture/needs lead to it?
who built it?
for how long had such techniques and maths been refined?
etc
The ROmans moved 2000 ton stone blocks, you cannot do that with log rollers etc, sheer weight crushes them and likewise it would drive itself into the ground if you tried ot pull it
ROmans didn't have UFOs, or magic so thus they must have had some perfectly good engineering skills/tools/tricks we don't know of
Example: One I found fascinating when I was building 3D models of Roman seige engines I studied up on them
somehow they managed to cure and use sinew ropes that were BETTER than the any of the ropes we have today for making "torsion springs" for ballistas etc (I am
not saying they had "stronger" ropes, it's the torsion "springiness", elasticity etc that's unique to those ancient ropes)
they must have came up with such techniques over centuries of trial and error.
There are hill forts in the Scottish borders who's ramparts are vitrified, turned to glass.
short of an atomic bomb nothing we know of can do that on that scale, they've tried for years in tests with keeping roaring log fires going etc but as yet, nothing has replicated that effect
do ya think the Rpmans had nukes?
no, it's more likely the builders had some trick of vitrifying the ramparts/walls, so they became one solid piece that shed rainwater,didn't erode as fast and was thus immensely strong for its time.
Doesn't rule out bizarre stuff but merely you don't
need "aliens/a-bombs in the Iron Age" etc to explain most things that are "odd".
I may never live long enoough to see these mysteries explained, which would be a shame, but someone, sometime, probably will, even if it takes hundreds of years
