So is the typical alien that we see at the end and is in all these alien movies made first in this film or is it an existing species and just pops up here.
If it was first made here, was it just because the creature implanted in the humanoid creature? If so then the chain of events would be infected scientist impregnating other scientist... her birthing/shorting a squid alien which face hugs an engineer, which causes a typical xenomorph to birth?
What about the deep throat snakes in the pyramid? did the black slime cause the meal worms to turn into that? then once they jumped down the throat of the scientist, why did it turn him into a miami resident and not impregnate him with an alien?
Actually why didnt he start to disintegrate when he drank the shit like the engineers did?
