maybe it was aliens, maybe the egyptisans were just smart. its just hard for me to believe that were the only planet with life on it. but well never know till we really know right:dunno:
I believe in life on other planets. Its almost impossible that there isnt life out there somewhere. I also believe in intelligent life on other planets. But I dont believe aliens have visited Earth, and if I had to guess I would say Earth will never come into contact with other advanced life because of the distances involved in space travel.
