xenomorph evolution a fan can appreciate

heres my take on the black goo and the xeno connection what if the xenos werent engineered but rather back engineered like a natural species that the engineers wanted to make more compact and controllable (the black goo) this would explain why the lv 426 ship had a fossilized space jockey and eggs instead of ampules because they hadnt perfected the virus yet all they had was a way to keep the naturally queen laid eggs in stasis. so the lv 426 ship was ancient and not related to prometheus at all. black goo is the final result a virus based off of the xeno dna. one more thing the reason for all the mutations in this movie is because the virus wants to get back to its original form of life ( first the squid baby then the xeno) naturally (shaw and halloway mating). this is just what i gathered from the movie so there are definate connections one thing can be certain though prometheus is not how the xenomorph formed my evidence is the murial and the fossilized space jockey because obviously 30 years is not enough time to fossilize we can deduce that the xenomorph in the form and life cycle we know and love is at least as old as the lv 426 ship and was not created through the evnts of prometheus... ne thoughts
