It's true that astronomy can produce some very very big numbers, and I am
impressed.

Maybe, but biology can produce some very very big numbers too and it's not
at all clear to me that astronomy's numbers are bigger than biology's. And
even if what you say is true due to the acceleration of the expansion of
space by the time intelligent life evolves on those enormously distant
galaxies they will no longer be in our observable universe.
