Following on from the thoughts about the apparent absence of Extra-terrestrial intelligent life .
The stars in our galaxy are going to be roughly the same age ,though we have found some that appear to be as old as the universe. Which , by the way , is consistent with the Unified Model but not the BBB.
Therefore it's plausible to suggest that 'Intelligent' life is in a current state of evolution.
Some much older and some much younger.
Then you have the huge distances between stars to contend with . Then there is the problem of what to do when you arrive at an Alien planet. Even if it had an atmosphere that we cold breath we would still need a space suit to protect us from all those alien germs. Imagine going all that way and being unable to even do a little shopping? !

So.....the question now is " can there be space without time" ?
I'm running out of space and time!
