I'll add something.
I'm sure that life has evolved elsewhere in this universe but I think when is the question. Even our own solar system is a rebuild from a previous system and we know this because we have heavy metals on earth which can only be produced in an exploding star.
They say the universe is 13.7 billion years old. We took 40 million years to get where we are and it's more than likely we will disappear within another thousand years, left to our own devices, so if all intelligent life has a use by date of 40 million years before it kills itself, there could have been thousands of intelligent life forms in this universe before us and after us.
It's quite possible that at this point in time we are it, but who can tell. The light we see from stars is only a few hundred years old which is really a drop in the ocean of time. We have only had the capability to look out there with electronic ears for something like 30 odd years. I think the question needs to be reviewed.
Did or will ET exist.
