Personally, I believe that there are other forms of life in our own solar system. Maybe not "intelligent" life, but
it does exist.
So it feels automatic that in all of the galaxies in this universe ~ of course there are other intelligent forms of life out there. There must be! Galaxies upon galaxies with millions of solar systems. Really!

I find it simply impossible to believe that we are the most intelligent lifeforms that have ever existed in this universe.
I think the show Twilight Zone was ahead of it's time and we've regressed since then. In the United States anyway. Modern civilizations are so focused upon ourselves and NOW, many people don't seem to even bother working with their imaginations & thinking about the future of mankind.
Like I said, those are my personal thoughts.
