Prometheus and covenant should not have existed in the alien universe at all because it was Ridley's attempt to ask a different question than the ones the fans even wanted answers for. Making the Space Jockey some man in a chair and space suit was insulting, especially considering the size of the creature in the chair was way larger than the "engineers". Saying that humans were seeded by humanoid aliens from space is also stupid within the universe the original movie suggested. And the concept of the black goo is a totally over used trite scifi trope taken from the X-files, the Matrix, and a couple others i cant remember. Disappointed.
