do you believe that aliens did visited us during ancient times?

I saw a documentary on the opposite. It suggested that each possible theory had an alternative reason. It said that stonehenge and pyramids were possible to build using older methods of construction, religious beliefs led people to make large drawings in the earth and space pictures were designs practiced by them for various reasons. I think they took babies for example and made their heads a different shape by wrapping them, so they would look different than anyone else therefore special, if I remember correctly. I am not against the idea of aliens, as that would be so interesting but my science teacher sort of spoiled it for me when he explained the distances involved. Something like ten thousand year trips are needed to reach other galaxies unless something like a worm hole is possible. That might be science fiction. In any event I do not think aliens visited but I do believe there was another source of life other than human kind in those times. :-)

I think that was the same program that claimed the Chinese race were descendants of aliens. All silly, unproven nonsense.
