Most definitely. No question in my mind. What I wonder about is if that is maybe where we have gotten some of our recent jumps in technology.....almost like there is someone helping us. In fact, I'll go so far as to say that it would not surprise me at all if they are amongst us, or at least around, watching, observing. If they have mastered faster than light travel, secrets of the universe, etc., I don't think they would be in any hurry to reveal themselves to us, a world full of nations that have very large weapons pointed at........each other.
The last time a guy came down here spouting great knowledge and words of wisdom, well, he ended up nailed to a cross.....and I really don't think we are much different than humans were 2,000 years ago.
So, yes, I'm sure there is life out there....there has to be.....but I wouldn't be expecting the human race to be given a seat on the Galactic Council any time soon.
If ever.
