This is whyAlien: Earths premiseis such a big deal.
So far, it is unclear how much of theAlientimelinethe upcoming show will retcon, if at all.
The term"Xenomorph"was first used inAliens(1986).
The events ofPrometheusandCovenantcan be interpreted in two ways.
EitherDavid created the Xenomorphspecies that we first met in 1979sAlienor he reverse-engineered something that already existed.
Any other option would make theAlienfranchise a whole lot more complicated, especially with the arrival ofAlien: Earth.
