I believe in extraterrestrial life, and intelligent life elsewhere in the cosmos. I do not believe we will ever make meaningful contact with that life. It would be awesome, but the odds are astronomically against.
There's a slight chance that they are, but I seriously doubt it. Scientists HAVE discovered new worlds out there, similar to ours, with their own "suns" and "moons" which I find highly fascinating. LOL If aliens are real then when they get to earth they will be more far advanced then we ever were.
