Prometheus from my view

The engineers created life on earth to test their biological weapon, the xenomorph, which is obvious that the project wasnt fully completed due to an out break that turned on them. 2,ooo years before the out break they decided the project was ready for a test run, out break happen, the test wasnt carried out. The goo that David found was goo that belong to a xenomorph and due to the fact that the incident happen 2000 years before they got there, on an isolated lifeless planet, it would be hard for any xenomorph to remain alive for so long. But the goo, thanks to the terra forming was preserve with out any issue. ------SO there you have it, the truth about Prometheus, after viewing the movie 5-6 times, the movie makes sense to this and it even supports this theory. SO lv 223 is Area 51, and planet earth and its living organisms is where we would test our toys that we build at area 51.
