Do you believe in the Annunaki's?

I've been doing a lot of UFO research lately, and the likely hood that we have made contact with an Alien Race ( annunaki's) seems very likely. No it doesn't disprove any religion, quite contrary it collaborates with the stories of the bible, specifically Noah's ark. The annunaki's were believed to be 10 foot on average, and to have genetically altered our the cro-magnons so that they evolved into humans. If you look at humans and cro-magnons dna sequence, all the genes are the same but 2, which the Annunaki's are believed to have fused. Also it would explain a lot of historical phenomena such as the Pyramids, Atlantis, Stone-Hinge, the source of the Mayan predictions, the building of Sumeria. Also consider they are mentioned in the sanskrit writing, The Vedas. The quaran says Allah is the creator/ god of ALL World"s." Also to me, I just don't understand how egyptians could have made those pyramids so perfect with the technology they had. Same with the Mayans, how could they have had more knowledge of the universe than current science? In the Sumerian text, the solar system and it's nine planets are shown, but also another planet which the Annunaki's are believed to have come from- Nibiru. I know it sounds like a load of crap/bs, but have you also noticed that our common idea of aliens being gray like with big heads comes from the Annunakis? they supposedly created an android-like race to help assist them in the mining of earth. Also the government has a tendency to hide things from us for better or worse. So if they have met and given us information, maybe the government hides it from us because it could drastically change our civilization. Much like how parents don't tell there kids they are ill because they don't want them to worry. Nasa has also blatantly lied to us. I know this all sounds like a load of bs, but if you look at the evidence is it really that unlikely? I highly highly doubt we are alone.
