The Origins of the Space Jockey Race

One must consider that the derelict ship in Alien is one of many and that Prometheus may take place at another place and time. I think that the SJs are drones that are programmed to spread the seed of kings throughout the galaxy. Once they discover the location of a new race the has been "invited" to their location, they launch a drone (aka derelict) ship to continue the species.

So what the Nostromo crew thought were bones bent outwards are actually just some kind of automatic seatbelt, and SJ's are more or less humanoids in suits with funny helmets?

The Space Jockeys are an ancient race of exiled intergalactic wayfarers. Yutani records suggest that contact with the Yautja led to all out war. A series of events took place that resulted in the evacuation and destruction of the Space Jockey homeworld. It is believed that in a last ditch effort to end the Yautja conflict, the Space Jockeys used their advanced knowledge of bio-engineering to create a race of more intelligent and highly dangerous Xenomorphs. Once the modified Xenomorphs were unleashed the Space Jockeys found themselves facing a threat much more dire than the trophy hunters. The Space Jockeys managed to deter the Yautja but it would come at a high cost, the price of their homeworld. Facing extinction, the few surviving Space Jockeys took to the stars in search of a new home. They loaded the remants of their once great civilization onto their mightiest space going vessels, and set off in search of a planet rich with resources and bio-diversity capable of sustaining a fresh start. They wouldn't get very far. The Yautja, fearing that the Space Jockeys would again unleash their Xeno plague descended upon them with ferocity. Only one vessel is known to have escaped, the ship known as The Derelict.

new theory for the plot I thought I'd put out there after reading a few. The space jockeys technology clearly looks like its based on bio technology. The ships look organic and the chair grows into its occupant amongst a few uses of bio technology (not to mention several other bits of evidence in the trailers). There ships also look alot like an alien hive on the inside. Maybe under space jockey control, xenomorphs can be directed to build their hives into space jocky ships and structures. So Aliens are kind of like the SJ slave work force. Secondly maybe the space jockeys are originally evolved from a virus or bacteria (kind of x-files similar plot I know), the black ooze found in the pods in chamber with the big head. This ooze/virus infects other races and mutates them into space jockeys. A race that uses other races like that to reproduce would have no trouble with using other organic life as a kind of resource to build up their spaceships. Plus we know they are old (LV-426 space jocky was fossilised). Bacteria is one of the first forms of life. Imagine how much it could have evolved if we're talking on the cosmic scale with billions of years. So anyways I see it as something kind of like intergalatic farming for them. They leave clues on primitive worlds to wait for the population size to get advanced enough and big enough to reach a dormant SJ ship. The human crew's curiosity leads them to being infected by the SJ virus/DNA and becoming a space jockey themselves. The space jockey goes back to earth to "farm" us like a good alien farmer culling his herd. Some humans are infected to reproduce space jockeys. others are infected by aliens who make more ships under SJ control to spread to other worlds and repeat the process. Other thought that popped into my head. The space jockey suit also looks organic in nature. if the SJ use other species to reproduce and grow their technology maybe one guy gets infected and slowly turned into an organic SJ space suit, while another gets infected and turned into a just a space jockey (the blue head guy in the trailer), hence some differences seen in the clips of mutated crew members. Thoughts and opinions on this would be muchly appreciated fellow film geeks.
