In this post i will talk about how intelligent aliens are. As you know aliens in every alien or avp movie have been brainless almost but I wonder how smart the xenomorphs of xenomorph prime are? To ask how smart they are is one of the best questions u can ask about the alien universe, so i'm going to explain my opinion on how smart they would be on their planet. Since the aliens of xenomorph prime dominated the other species there they must have some intelligence , but they also lived there for billions of years( im guessing ) so they must have a semi slow development rate of intelligence so I believe that the xenomorphs there are capeable of constuction of tools and buildings.
