The chemistry and physics of our universe requires heavy elements for the genesis of life. Heavy elements are only produced by violent fusion transmutation processes during the death of super nova stars. Much time must pass from the creative "Big Bang" to when sufficient heavy elements are available for incorporation in the birth of stars capable of hosting a planetary system of rocky planets with heavy elements essential to host life. (~9 billion year).
The conditions required for life in our very hostile universe are very limited. A planetary system must have formed in a narrow habitable zone within it's galaxy where there is sufficient stars with heavy elements and far enough from sterilizing radiation from the galactic core. The system then must have rocky planets with stable orbit and axis tilt within the habitable zone of the system. Such planets must avoid destruction from space debris and remain quiescent for at lest a billion years to nurture life. The probability of a technological civilization arising serendipitously and surviving itself is very low.
This makes our planet fortuitous indeed and perhaps among the first to host intelligent life in our 13.8 billion year old universe. Predation and violence seems a critical element of developing higher brain function. Such life is not likely to survive itself long enough to create star ships. So it is highly improbable that ET has originated in our known universe and they can't be much more ancient then are we.
Here be the conundrum: We have significant evidence of ancient alien intervention and have ongoing communication with other worldly beings we call the "Ancient Ones" claiming to be three billion years our senior. I have encountered a "shadow being" who vanished in plain sight.
I was an operative in our nations Star Gate Noetic program and have experienced the presence of these Ancient Ones. Star Gate evolved from Scanate remote viewing project and has now achieved bi-location. We have only encountered inter-dimensional beings.
