aircraftfixerJuly 19, 2012For me, this analysis (the link, that is...) is ten times more captivating than the film itself. The author of the article; for the most part, addresses the most important question that the film asked: What happened on LV-223 2,000 years ago?
In my opinion, the theory presented in THIS article would have made a splendid screenplay for an actual "Original Story"- to be viewed by any audience- even those not familiar with Alien. It could stand on it's own, but still be in the same universe AND count as a prequel too!! 
Eureka!!
...Then, the events shown in "Prometheus" can be shown in an entirely different film production. Everything will then make sense, be entertaining and significantly limit all of the wild speculation that it (by itself) caused.
Even Shaw and David-Head will be apt to focus on finding the answer to a much more direct question. Their discovery at the other end would be either Positive or Negative- instead of being a completely unpredictable mystery; Complete with unlimited possible outcomes and even more questions...
If this article's theory was indeed the script for what would be filmed before Prometheus, perhaps Shaw, David-Head and the audience will also be able to make sense of why the events on LV-223 were never (apparently) investigated less than 2,000 years ago by the civilization on their "Home World".
