> Even H.R. Giger was boring and unimaginative with regards to how he envisioned the Alien. That's clearly a creature influenced by Earth-ism - a quadruped, with a single head and mouth and a flexible spine and claws, it's basically a weird cat.
When the franchise came into being, you're probably right. But in all fairness, the back story and the biological concepts in the Alien universe has been refined since then. For example, the human-like qualities of the xenomorph creature is now explained by the biological merger of an alien substance with the host. When a human was infected, the substance developed into a parasite that took-on characteristics of the host.
Fundamentally, the black goo (i.e. the substance) we saw in Prometheus was pretty much the source of all the alien creatures. It was basically an instrument that deconstructed existing life forms and rebuilt weaponised variants of them.
