I think it is very possible that they had contact with aliens. Judging from what we can see in the country, like the great pyramids constructed with those millions of huge blocks put symmetrically together. I don't quite believe that it took millions of years and was built by hands of humans. The culture of Egypt is something intriguing, the hieroglyphics, the fact that they could manipulate electricity and fire, their legends of immortality, the mummification and how the pyramidal hierarchy was settled. Another interesting thing is that a pyramid is said to be the most appropriate geometrical form for getting solar and spiritual energy and some say that the pyramids were constructed considering this factor, so the energy that came in would go from its tip to the very centre of it and the pharaoh would meditate inside of it and get in a higher meditative trance.
I do think that they had contacts with higher beings. The sumerians also registered contacts and even described an ancient language allegedly from the outer space, Anunnaki, which means ''descending from the skies''. They were great observers of the sky too and some of their hieroglyphics describe the solar system and nine planets, which would be obviously impossible without the current higher tech.
