My Theory. Whats yours?

The world is a very different place. Society has evolved into laissez-faire capitalism and corporatism. During this time Peter Weyland emerges. He is brilliant, cold, and ruthless. Take the genius of Steven Hawking, mix in Steve Job's charisma, and add the negative traits of todays CEOs (Bill Gates, Robert Murdoch, Larry Ellison). The company he creates is called Weyland Industries. He not only grows the company with his inventions, but he lies, steals, and cheats into any sucess that escapes him. Nothing is permitted to interfere with achieving his goals. Over the years he gains monopolies in one sector after another through manipulation and political trickery. Through constant mergers he soon controls defense, energy, health, and other countless other critical industries. While governments remain Peter Weyland is very much in control. The company builds the star ships. They make all the armies weapons. They provide eletricy, media, almost everything. Waring with Weyland Industries countires under control of asian rival Yutani Corporation provides distraction for the masses. Problem is Peter Wayland is very much human and he's getting very old and sick. Now 83 he's used technology to live longer than his failing body should allow him to. Desperate. He finds his answer in some archelogical discoverys. They indicate at some time in the distant past we were visited (if not created) by alien lifeforms and they left the locals with a map of what could be their home world. From here you can tell they visited the alien world. My best guess is the aliens created man in their image, as they have similar features. They may have created all life on earth. As this likely occured thousands of years ago, the aliens must have an extremely long life span. Their technology rooted in biological engineering and bio mechanical constructs. Some time during their exploration of the alien base (inside their ship sits), something goes horribly wrong. I'm guessing Peter Weyland (or those loyal to him) direct the crew into doing something unwise in his eagerness to have the alien technology for his own. Looks like some people get mutated and a bunch of bad things happen. This likely pisses off the alien (or aliens). Being the creator of life, they have also created tools to destroy it. Including a sealed bays of thousands xenomorph eggs. Depsoited on earth, over the course of months they would make short work of the human species. I'm sure the alien give some sort of speech or indication on whats about to go down. Realizing they are screwed the crew rams the alien space craft as it attempts to leave for earth. I wouldn't be surprised if this totally destorys their own ship. It's unclear what happens from here. Perhaps the alien ship uses its ability to bend space/time to move to another planet (LV-426) where the last alien dies from a chestburster. I wouldn't be surprised if everyone dies.
