So, as we probably all know, the backstory and history of Alien has been retconned to hell and back over the decades. And through the entire affair, Weylan-Yutani basically became more and more omnipotent. They essentially went from knowing about the Xxenomorphs to knowing the location of the Xenomorphs to breeding the Xenomorphs, all before Ripley even set foot on the Nostromo.
My question is, how much did Ridley Scott intend for the then-unnamed Company to know about the Xenomorph before Alien was released to theaters? For example, did they just know of its existence? Did they know what it looked like? Did they know its history or its exact location? Depending on where in the franchise you look, you get vastly different answers to all of those questions.
That means interviews, unshot footage, cut scenes, drawings, whatever, so long as it was put on paper before the film released.
