Aliens (extra-terrestrials)?

FYI, thinking about another life form having bested mortality makes me incredibly jealous and upset."

Well, get used to it because that has almost certainly happened. I doubt our own civilization is any more than a few hundred years from it.

Personally, I think we haven't encountered them simply because the universe it THAT BIG. Perhaps they are "god like," in terms of how advanced they are, but even then, the universe is so big that even for a god like creature there would be a very small chance of ending up anywhere around our vicinity, let alone our specific little planet out of the huge amounts that are out there.

You should go back and re-read Fermi's Paradox. The whole point he makes is that it's NOT that big. A single technological civilization could colonize an entire galaxy in a relatively short time - if they desired to.
