The first guy created us is the betrayer

The guy created us is the betrayer in his companions' eyes just as PROMETHEUS. That is why the the engineers want to kill humans. I don't think the engineers created human beings. The human beings are an unexpected specie to them. The first guy at the beginning of the movie who drank the black goo is obviously like "PROMETHEUS"---The betrayer of the other gods. He sacrificed himself to spread high-level DNAs on earth just like PROMETHEUS gave fire to human beings. AND it is his individual decision and behavior. In the movie, he seemed lonely and the backgroud is his fellows' leaving airship. If it was their common decision, it should be more reasonable that there was a ceremony for his great sacrifice. When other engineers found humans which were the same or most similar high-level creatures like them were created. They felt kind of competition and anger. But as humans were in development and our tech were far behind them, they have plenty of time to observe us and the paintings in the cave are the prove. And when our society become mature, they will finally test their bio-technology on us to see the results since our DNA match them best and we should be the best testers. The guiding map is a trap or death invitation or death warning. That is why they created us and then want to kill us. Actually, one of them betrayed and created us and the others are waiting a best chance to kill us. That is why the engineer waked up by humans immediately decided to kill humans. It was their plan to destroy humans but the plan just hadn't been executed because the bioweapons they developed were out of their control and killed themselves. I think the engineer we found was a survival one and he knew the severity of the status. He will continue the plan to stop humans' development. They think we are threats to his mother planet. They don't want humans to be equal as them just as we created robots to serve us, but when robots want equality and they are out of our control and dont want to be just servers,what will they do? And what will we do? Creators have creators. Finally, forgive my poor English.
