avp and alien timeline issue

New to forum come mainly to talk about the timeline issue with the alien, prometheus,predator,and avp movies I think I made it make sense. Well it's the only conclusion I can come to is kind of long and out there but the only way it seems to make any so plz bare with me. So in prometheus at the very beginning one of the promethean people (that's what I'm calling then because i forgot their name plz correct me) sacrifices himself or commits suicide with what seems to be the same liquid that the Xenos come from.... Any way he falls in the water which seems to start crating life on earth. was this an accident? Since he was being left behind? This is were my story starts to maybe make sense. The prometheans leave earth not knowing what they did but still have coordinates to earth maybe their shop was intercepted by a predator cruiser or the predators were at war warwith the prometheans and discovered the xeno bio weapon, and the coordinates to earth? So predators take xenos to earth and start the hunt (shown to us in avp). The predators lose a couple of hunts with the xenos on earth and decide to just hunt the human race since we are becoming more dangerous and stopped worshipping them. Then comes the first predator movie where the predator is hunting humans. Then the second predator movie comes which I agree didn't need to be made the only relevant part was the trophy room because it shows how long they've been hunting and how many different species they hunt. Then comes avp, maybe the predators got bored hunting just humans and wanted to hunt xenos again so they go to that pyramid fighting ground and start the hunt. Then comes avpr which explains the abomination and our governments discovery of the xeno infestation which they quickly put to rest with a nuke. They also recover a piece of predator technology which probably does advance our technology. I think predators comes next because human technology has yet to be as advanced as the movie prometheus. Maybe the predators decided bringing the xenos to earth was a bad idea so they brought us to a game preserve. Then comes prometheus which is humans first contact with the prometheans and xeno in their bio weapon form. In this movie is when the xenos break free and this planet probably becomes xeno home world. Then come the alien movies because the xenos are free and we have to stop them from getting back to earth. So that's it ours long and kind of confusing but in a way makes sense. So movies go as follows predator, predator 2,avp,avpr,prepredatorsdators, prometheus, then the alien trilogy.
