1. One Of The Engineers In Prometheus Was Jesus Christ
Prometheus is full of religious symbolism (Shaw's crucifix, the creation of life theme, etc), which is something fans noticed, and decided to take a step further: what if Jesus Christ was an Engineer?
In the film, we learn that the Engineers - powerful, god-like beings - were trying to destroy humanity by using the black goo. Why? The fan theory states that this is because the Engineers had decided there was no hope for humanity, after the humans crucified someone the Engineers had sent down to guide and aid them - a man we know as Jesus Christ.
When asked if this was something he considered while making Prometheus, Scott said that he "definitely did", before adding that he thought it might have been a little too on the nose. He then discussed the idea even further, lending it his support:
"But if you look at it as an 'our children are misbehaving down there' scenario, there are moments where it looks like we’ve gone out of control, running around with armor and skirts, which of course would be the Roman Empire. And they were given a long run. A thousand years before their disintegration actually started to happen. And you can say, 'Let's send down one more of our emissaries to see if he can stop it.' Guess what? They crucified him."
This certainly adds another layer to an already complex film, but in a franchise that started off as a simple contained horror, it's hard to say if these extra layers are really necessary.
