And how do you know this?
Simple, and yet not simple. Either we are alone in the universe or we are not. Whichever option you choose to evaluate leads quickly to awesome conclusions. The God option brings a lot of responsibility with it, and is possibly more complex than the Sagan option.
It's possibly more complex in this way: If we are God's only creation, we have a lot of growing up to do, a lot more than just trying to qualify for membership in some Galactic Federation. At this time it appears that we are alone in the galaxy at least.
Apparently you didn't get the memo from God that stated the REAL situation with this. One has to wonder what you did to get bumped from the distribution list, if you were ever on it. But since you obviously weren't intended to be privy to the facts, I can't disclose any more. Sorry.
