What about the Ideas?

According to me behind the whole film concept stay some "Alient-nothing-to-do" ideas. For instance those bitches are really Engineers which has nothing to do but mixing DNAs all the time and see what will happen. The first Proto-what-ever-it-is engineer was sacrefied on Earth and in million years his DNA combined again in a way it was in the beginning and human appeared, they were close to see what had happened got frightened that humans can be stronger than tehm (because humans get something new for them - soul) and decided to kill them. Here also comes the God story and the human soul. About the Alien they tried to reach a certain prototype (we saw it on the wall) as mixing DNAs - engineering but when they finally did things got out of control. Bottom line those are some bitches playing Gods but nobody can play God (Nature) but the God (Nature) otherwise he pays for that....
