Peter Weyland is Prometheus

Long time lurker first time poster. Anyways, here's a theory that keeps popping in my head. Maybe its already been touched on before, idk. Peter Weyland is Prometheus, metaphorically. He is the one who drew all of the pictograms across different civilizations throughout the centuries. His punishment for helping us along, was his fellow Jockey/engineers turned him human and he is destined to grow old and die and be reborn throughout time. That is until technology finally catches up and he is able to travel back home and try and restore what he once had...... No real weight to it and it most likely will not be the case, but I Just thought it would be an interesting spin on things.... Also I think the whole "A king has his reign, then he dies. Its inevitable" speech is Vickers talking to Weyland once she reveals her true colors. At first you think she's the cold company woman, but later we're supposed to find out an alterior motive of hers.  Perhaps "a king has his reign" is what she tells him right before she kills him or puts the kebosh on his immortality plans to reveal her good intentions...... Just speculation and sorry if its been mentioned already. Peace, guys. Great site. P.S. please tell me I'm not the only one who thinks the Weyland company logo looks exactly like the serpent/cobra like alien when it spreads open.....Possibly a creation of P. Weyland/Prometheus that almost wiped out all the engineers before they banished him to earth
