Why can't they make a pre-quel

Without making it obvious it is a prequel, but basically making a story that the local girl in the original talked about, if you remember, set up the same jungle of the original film, and show how predator is hunting the indigenous tribes in the villages there, let's say 4000 years ago, no modern equipment in terms of weapons, now that story of the film can be a truly horrifying fable, let's say come up with the local warriors who start standing up against Predator. And the whole film would probably be about fighting him, but the warriors would be also discovering themselves through the journey, and how much predatory their own instincts are destroying their lives, so it would be about something deeper as well that would make them realize why Predator exists in their lives and how their Gods can help them make it go away (which the original film never explored as the story was very straight-forward and empty in terms of character growth) but I must say, at the end they would never defeat him, so he would be still alive until 1987. I really believe Predator is ageless, not fully dependent on the aging element of the oxygen, or at least he's able to live as long as some of the oldest trees on Earth. This kind of a story Ive been waiting for since 1987 when I saw the original, why setting it in the present, go back into the past, and explore the nature of this creature or where he comes from, and why coming here on Earth, that is more exciting, because this is a very primitive creature in a primitive environement, the moment you set it in the city or within any modern area you lose the appeal and potential of the film. I say, go into the past.

Also one key thing these filmmakers forget, jungle setting is one of the main things why the original was so appealing, it is claustrophobic in a way and primitive by helping us to face the raw nature of who we are, it's as much important as the Predator itself.
