Meaning of Prometheus relates to religion

I'm not religious but i found the constant inclusion of faith a possible way this film could be interpreted. It is assumed that the Engineers are the creators of human life and are worshipped by ancient civilisations as the Gods as, realistically, they are. The creators of life, as we assume from the opening scene. The movie is based in 2091. When they test the dead body that was decapitated they say it has been there for approximately 2000 years. Approximately 2000 years earlier, Jesus was born and hailed as the son of God. As the real God of humankind, how would you feel if the species you created started praising and believing in a God that was not yourself? We know that the engineers were intending to head to Earth to kill mankind, maybe this was their way of teaching their creation a lesson for no longer believing? You have to remember that the engineers were planning to head to Earth 2000 years earlier, well before we had the technology to meet the engineers. The fable of Prometheus is that he took fire from Zeus (THE God) and gave it to humans. Perhaps our newfound faith insulted these Gods and Jesus, as Prometheus did, took what was Gods gift and gave it away and this was the engineers way of redemption. Just a cool way of possibly interpreting it.
