What came first, the chicken or the egg? (metaphorically)

I've read lots and lots of posts and been racking my brain for the past few days. Here's the basis of my simple theory...
In the age old debate of "what came first, the chicken or the egg?" there is no clear answer, right? Well, I think I can apply this same circular logic to Prometheus, albeit hopefully make more sense.
Numerous people claim that ALIEN is "million-year-old tech" that supposedly predates the Deacon or "Proto-Xeno." My philosophy is that the true Xenomorphs come from facehuggers which come from eggs which come from a Queen, which comes from a facehugger which also comes from an egg... yada yada yada.
This is the same chicken and egg debate... which leads me to believe that the Xenomorphs of ALIEN are created, not a naturally evolving, self-sustaining life cycle of: egg-host-creature.
How are they created? The "Black Goo" or primordial soup as some have called it, seems to me the most logical explanation. I originally thought it to be purely mutagenic, until I realized that everything biological it touched caused it to become ALIEN-esque, meaning the same DNA responsible for the creation of the Xenomorphs, is also the basis for creating many other things.
The green, Jurassic Park-looking thing in the chamber, could be the source of the DNA.. and the Black Goo is what the Engineers created through experimentation with it.
My personal opinion is that the Black Goo does not contain actual DNA, but rather [i]recombinant DNA[/i]. This recombinant DNA can splice into the DNA sequence of any organism, with a plethora of results, which are purely random, unless engineered in a lab under a controlled environment.
