They knew about the Aliens and the Predators. Answer in detail, correct, additional points

I saw a comment in a Xunlei movie:
According to the world setting of the Alien series, this kind of thing was originally a biological weapon developed by the Malakak people. However, in the end, they could not control it and destroyed themselves. The Malakak people were the giants who had turned into fossils on the alien spaceship where the Alien was discovered in Alien 1. Humans boarded the giant spaceship and brought the head-exploding beast to their own spaceship. It was the plot of Alien 1. I don't know if the new Alien prequel will involve this history, but the Predators will also be reloaded. The technology of the Predators might have also been taught by the Malakakaks. This was because the Predators had entered the high-tech era directly from a primitive society. The primitive society was still preserved among the Predators, but the technology was highly developed. Thousands of years ago, the Predators discovered an alien egg during interstellar travel and brought it to Earth. They used the head-hugging beasts and humans to cultivate a powerful alien for the Black Star Troopers to train in adult etiquette. However, the number of aliens cultivated on Earth increased. Unable to control it, the Predator gave up on dropping the nuclear bomb and left Earth. The Void Mother was locked in the pyramid under the South Pole. Human scientific research discovered a pyramid under the South Pole. Iron Blood felt a sense of crisis and once again came to Earth to stop the resurrection of the Aliens!
The first time I watched Alien was on pirated discs and I watched Alien 1 and Alien 2 in an internet cafe. He had only watched Iron Blood Warriors in the past one or two years. It was a little confusing. Who had a detailed history of the development of the Aliens and Predators? Don't make things up. Don't come if you don't understand. If no one knows, then I'll sort it out myself
I watched the movie " New Predator " at Xunlei, and the main character dropped from the beginning. There was no reason. Was there a connection? I've just watched it and haven't finished watching an episode. I don't know if there's an explanation later.
