I’m trying to recall the name of a movie in which the plot was of an alien attack on Earth. In which the main character is told that we are simply put/made for the purpose of aliens using humans as cattle to enslave us into a huge labor force. The movie uses Egypt as one of the scenes, and explains is that we where left in the planet Earth so we can multiply until the humans had a sufficiently large population (billions) as to be useful for the creators/aliens. Also this movie is from the late 80s or early 90s.
