Obvious Mirror ignored

What I felt was an obvious and always ignored design aspect is that the Alien itself is a biomechanoid, this means it is not just an engineered lifeforms with genetic "Engineering" it is a organic material used to build a Machine, the Alien from the first movie is an Android made out of genetic material. Androids on the other hand are machines designed to reflect organic material and appear to be living thus making David and the Xeno the same thing but from nightmarish, different approaches. Giger designed to Alien to be basically a living organic robot from the start, if you look at the alien its meant to look like it had gear parts and servos made from flesh all over it, not just genetics but something else. Personally I would have loved to have seen some of the crew kidnapped by the real space jockeys with their elephant heads and plugged into the ship in some horrific way like you see in Gigers artwork. Just buy his Necronomicon you will see what I mean
