Pyramids were unique to Egyptian culture. Why WOULD any other culture build a Pyramid as a tomb for their fallen kings if they didn't believe that it would confer any benefit upon their king in the afterlife?
The Pyramids were built by human means, no aliens required.
In fact, the only tall imposing structure that CAN be built using the technology of the time is a PYRAMID.
That is why the American natives built large stone stepped pyramids as well. Because it was the only large structure that they COULD build.
So are UFO’s technological or spiritual?
Do they need interstellar space craft in Heaven?
The Bible says they can descend to Earth and ascend to Heaven. It says nothing about flashing disco light disks being required.
Demons..
And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits upon
the earth, and on the earth shall be their dwelling. Evil spirits have proceeded from their bodies; because they are born from men and from the holy Watchers is their beginning and primal origin;
they shall be evil spirits on earth, and evil spirits shall they be called. [As for the spirits of heaven, in heaven shall be their dwelling, but as for the spirits of the earth which were born upon the earth, on the earth shall be their dwelling.]
And the spirits of the giants afflict, oppress, destroy, attack, do battle, and work destruction on the earth, and cause trouble: they take no food, but nevertheless
hunger and thirst, and cause offences. And these spirits shall rise up against the children of men and against the women, because they have proceeded from them.
These are the demons we deal with, that most confuse as aliens. The demons roam the earth and torment mankind, causing them to sin and everything else.
