Help me flesh this theory out

My interpretation. To me this filmed seemed like it was proving a point by forcing the viewer to interpret the film. The interpretation yielded by the viewer could then be used as evidence of the point being made. I thought that there were two main interpretations to the film. 1) We have a deeper meaning in the universe. The religious symbolism had some actual meaning. The space engineers were the creators of the human race. 2) Our meaning in the universe is trivial and explainable. The xenomorphs are the creators of the engineers. A sole engineer decided he was god or saw past his gods and planted human life on earth. The engineer in the beginning of the film was not the Prometheus engineer but an engineer doing his job as created by the xenomorphs on an unknown planet. All of the main points in the film can either be interpreted or taken at face value. Depending on how one interprets the events in the movie, either using only what you can see or using our innate need to ask why, the film will have a different meaning. I think the point was to show how far we have NOT come in human thinking. We still hold dear to the ideas that beyond all logic and reason are otherwise false. Exmple #1 interpreting who made us and why we are here. 1) We were made by some mysterious race of beings, may be engineers, for some special purpose. We are the center of the universe. A faceless killing machine like the aliens are nothing more that some sort of tool made by us or our creators. There is purpose outside the simple biological means of survival. 2) The engineers were created by the xenomorphs. This makes sense as they are biologically far superior to the engineers. In a Darwinian race they would outperform us in spreading their genetic material. The goal of the xenomorphs is to survive and spread their DNA around the universe (Darwinian). The xenomorphs created the engineers to terraform planets and prepare them for the xenomorphs. The fragile, less intelligent engineers were kept in check by a belief system of gods and meaning (biologically programmed). One day a prometheus engineer didn’t sacrifice himself on earth but instead stayed to live because he didn’t accept the religious ideas forced on him. He created a colony of people who lived not under the direct control of the xenomorphs. This explains why all peoples of the world have illogical belief systems to explain irrelevant meaning (Just stating an interpretation of the movie, I’m not saying one interpretation is better than the other). I think all aspects of the movie can be explained either way. What do you think? Please try to poke holes or add how parts of the movie follow these interpretations. I will respond to questions as quickly as I can.
