Hi All! First time poster, please be gentle!
So I have been pondering the back story of the franchise for a while and find that Promethius and Covenent really help crystalize ideas for the back story, let me try to sumerize here:
The Engineers are basically highly advanced NeoLudites. Notice that thier technology, the ships etc, are based on engineered biology, there are almost no machines. This is the central plot point in the series, and explains every thing else.
They fear AI (just like many folks in our society do). They are afraid of being passed and replaced by robots, machines, and AI. They are an ancient and highly advanced race, obviously, and could make robots as complex as David, if they desired, but they do not. I think that they are essentially trying to create thier god, through seeding planets condusive to life as they know it, with the black goo. They find such worlds, and seed them, and then return hundreds of thousands of years later to see how life evolved. Most of the time, they life is "inferior" to them in some way (as humans were). So the Engineers return to those worlds to wipe out the experiment and start fresh, as they were trying to do to earth.
The accident that prevented them from wiping out humans 2,000 years ago, was the fatal error in thoer plans. It allowed humans to advance enough to create the very type of AI that the Engineers were trying to avoid. Note that they tried to wipe out humans at a state where it was clear they were on a path to technological development, but early enough human history that we had not yet created advanced machines and AI. This is consistent.
When David returned to the Engineer home world, he must have made a transmission to the Engineers, probably something along the lines of "I have found your god". They would have all gathered in the landing area (as they did) in order to see this rare and meaningful achievement. David knew they would do this and saw it as a way to get them all in one place to bomb them. The ironical part, is that David, and AI was in fact the god they were trying to create in a sense, just not the one they were hoping for. He, like them, now wanted to "wipe the slate clean" and take up the evolution of his form of life.
Perhaps the Engineers had realized that they had reached the limit of what they, as a species were capable of in terms of technical advancement, without using machines and AI, and so were trying to "engineer" or evolve new biological, intelligent life that was better, and smarter than themselves, through seeding many planets and "playing the odds" that eventually a superior race would evolve, that they could then use to help them advance. In the end they were thwarted by the very thing they were trying to avoid (AI, machines, David..).
I would love to hear your thoughts, and my apologies if these ideas have already been posted a million times!
