"Even if there is only 1 intelligent civilization per galaxy where you have over 100 billion stars per galaxy with some galaxies sporting nearer to a trillion stars. There are over 100 billion galaxies in the visible universe, maybe more. So even assuming you have only 1 species per galaxy, that's still 100 billion x 100 billion possible life sustaining solar systems. Which is probably a small estimate. We know that the building blocks of life are present more or less everywhere in the universe."

Well, the obvious answer to this is that everything is short-term not on millions of years.


Support for this: globular clusters are thought to be a first-born object designed to quality specs. If intelligent life existed they would have a premier orbit from which to observe their galaxy in comfort and safety.

I think there's still other variables at stake. We only follow our own rules, that is, our perception of reality is limited to our standards, of physics, time, sensorial information, etc. There could be an infinite number of "realities" with different concepts and rules for "life". Extremely advanced civilizations might even coexist with us, in the exact space without the acknowledgment of each other. I think our concept of life is extremely "Earthlike" to the infinite possibilities of the cosmos.
