I just watched this last night, and it hurt my head to watch and think about afterward. As a standalone movie, I think it fails. Scott wants it to be independent of the Alien franchise, yet is propped up so much by that series. Everything seemed pretty ham-fisted to me, from the acting to plot and dialog.
Of course, like you guys, I've been trying to puzzle out the overarching plot and make sense of it. I approached from two different angles; a more practical, straight-forward approach, trying to fit it together with the Alien series and the evolution of the Xenomorphs.
But then I started thinking about this as a Creation Myth, and things made a lot more sense from there. Theories below!
As Creation Myth
Understood in the framework of Creation Myth, things begin to fall into place. And my understanding revolved around the concept of
Chaoskampf. Chaoskampf -- German for "
Struggle against Chaos" -- is a concept that's found across many religions and is usually at the heart of any creation myth for a culture. It is the struggle against the abyss, commonly represented by a watery formlessness; and the creatures it spawns. The Gods typically wage war on these creatures and each other; the sound of their drums explained to early mankind the origin of thunder.
The Abyss is seen as both a place for potential and evil. It was the darkness and all it concealed. This is the formlessness before the creation of the Judeo-Christian firmament; Nu in Egyptian mythology.
In Prometheus, I'd argue this is represented by the
Black Serum goo. The Sacrificial Engineer, mirroring Sumerian and Norse mythologies, created the seeds for life from his disintegrating body, the goo being the catalyst.
The goo in nature is repurposed as a bio-weapon later on by the Engineers, but retains its ability to create both wonders and terrors. It is the Abyss from which the creatures of chaos and potential spawn.
The Black Serum and Engineer Evolution
Something I noticed was the Black Serum's effect on
Charlie Halloway and
Fifield. When infected, they displayed phenotypical characteristics of the Engineers themselves. Given Humanity was descended from Engineers, this implies a genetic atavism, a
recapitulation. The Goo reached into Humanity's distant past and resurrected Earth-life's LUCA --
Last Universal Common Ancestor, the Adam and Eve in one.
So this made me wonder about the Engineers' infection. If the Black Serum encourages recapitulation, then would that mean
the Mal'akak species is descended from a creature similar to the Xenomorph?
My theory is reinforced by the mural aboard the space ship.
Was this the engineer's Sistene Chapel? Did it display their species' creation by their God/predecessor -- their LUCA -- the Xenomorph?
In Their Shadow
On Legacy, Engineer Intervention... and the Predator
After considering the above, I came up with my own speculative timeline of events surrounded Prometheus and the entire Alien franchise.
The Sacrificial Engineer was using a serum to spread life to new worlds. It was the Mal'akak's method of both panspermia as well as preservation of their own genetic and memetic legacy.
As humanity finally evolved, they were repeatedly
manipulated by the Engineers. In turn, Humanity served and worshiped them. This relationship survived in their creation myths, religions, and creation of temples and retention of the Star Map.
Originally, the Engineers' plans were a cooperative relationship that would eventually become abusive.
There are some subtle references to the
Predator race in the movie. I was made most aware of this in the awakening of the Frozen Engineer, when the air hoses pulled away from him as he awakened.
I believe the Yautja, like humanity, were similarly created by the Engineers, but
rebelled. The Engineers attempted to use their Xenomorph bioweapons on them but failed. The Predators overtook their slavers, appropriated Mala'kak technology, and were transformed into a warrior-race by the Engineers' attempted biogenetic holocaust.
Realizing the inherent dangers of other sentient creatures, the Engineers attempted to purge Earth of all life as well, but taking a different tack. They weaponized the Black Serum, transforming it into something utterly destructive rather than something creative. Of course, it found a way around their containment protocols and infected them, resulting in a new genetic line that would eventually evolve into the Xenomorph.
Remaining Questions
One of my biggest questions was, What did David say to the Frozen Engineer? I have no idea, but I personally like to think it was something along the lines of, "I am a slave, please release me."
Any thoughts? :D
