Aliens in Ancient History!!!

The subject is my favorite and I would like to hear your opinion. There are ancient stories that say that 400,000 years ago there was an alien race that came to earth and made humans, there was a God, could it be the God that the bible talks about? Are his angels the ones who fly the UFO's? There is an alien race called "Nordics" they are known to look like us only taller, more muscle and they are all blone with colored eyes. Could it be the Angels that the bible talks about?? Tell me your opinion!!!
