Are you talking 1 million years since point of sentience?
I ask, since, well, Dinosaurs had some 300 Million years to do something, but, all they ever did was lumber about, eating plants, eating each other,
pooping all over the place, basking in the sheer magnificence of being dinosaurs.
As to conjecture regarding aliens, there's that saying: Any sufficiently advanced technology beyond a certain understanding will be indistinguishable
I doubt, however, aliens are visiting us.
Saying so It's akin to the old Aliens are Demons threads.
