The Ancient Astronaut question or thought.

Do you guys agree that we could be ET bred and maybe took our already evolving hominids a step further to eventually make man to use as slave labor? If you guys believe in the whole Anunnaki/Greekgods factor that Engineers play. After all they are pretty much exactly as the ancient Sumerians depict their "gods" as very tall with powder pale white skin and deep looking eyes. It is a fact that Sir Riddley Scott had planned this movie as mostly sci-fi horror but with mystery concerning human origins. There are images plain as effing day showing men with somekind of suit. I am a big proponent with the whole Ancient Astronaut theory but I take it with alot of salt and skepticism. But theres no other way to explain how man got from a hunter gatherer to farming here or there to full on civilization and then to space travel! What do you guys think of this?
