Pretty intresting, as i said i believe in religion that there's no god, there is only aliens, and we are they colony called planet earth, we'r being controled by them, anyways, here's video : http://www.youtube.com/watch?v=wrYiiqGBWe0

I totally say no. If they came, built pyramids, and left... Whats the point?
Also...
I believe the Egyptians enslaved their own people, and forced them to do the work. It's much more believable than Aliens. And the people back then were more fit, so the work wouldn't be as hard. They actually had to work for food, so they were more toned.
Fact is, it's not possible to do what they did. the surface area of the blocks and the amount of people that can fit under them, it just doesn't work, they would need to have superhuman strength. Sure they may have been healthier back then, but it doesn't mean todays generation has devolved into slush.
The only other thing they could have had was some sort of advanced pulley system, perhaps they had a man-powered crane.
Or... Since you buy into Aliens, maybe the Ancient Gods came down and assisted them. If you can use Aliens as a solution, I use Gods, which is way more likely because the majority of the world believes in them.
