Prometheus uses interstellar travel in 2089. That's only seventy years from now,

they got the Predator technology to Yutani as shown in the end of AVP Requiem.
But that depends on the Predalien birthed in AVP and acording to AVP human
civilisation came from Predators who used us to birth Aliens. So the only
reaonable way for Prometheus to get LV 223 is if Aliens are ancient.

But Covenant is a sequel to Prometheus, and it shows the creation of Aliens
isn't until about 2100. So how did Aliens appear thousands of years ago if they
aren't created for another eighty years?

The aliens were not interested in us until just recently.
