Come fly with me

The
ancient
pyramids
got their shape
from varying pieces
of stone that were placed
side by side, on top of each
other to form a triangular image
that has lasted thousands of years
and could only have been accomplished
with complex plans and the greatest of care.
It's hard to imagine that such a feat was possible
outside of modern civilization with the only machinery
being the bones and muscle of man, yet there is no other
explanation except that perhaps some alien culture of beings
created marvelous forms which eventually became known as one
of the wonders of the ancient world where Pharoahs were laid to rest.
