The estimated number of stars in just our own galaxy is about 400 billion.. About 80% are small, dim, M or K type stars which tend to be unstable flare stars. Another 5% perhaps are giant stars with short life spans. Of the remaining 15%, perhaps 1% of them have planets similar to Earth in their habitable zones. Maybe 1% of those develop life similar to life on this planet, and 1% of those intelligent life as well. That’s 60,000 planets with intelligent life, just in our galaxy. There are about a trillion other galaxies in the visible universe.

One can always fantasize and speculate, but that is all there is.

Statistics look credible. But then, one has to look at all the other conditions that have to be statistically met for life to have been "created", and then, from that life-form, there would have to be conditions that also need to be met before any kind of life form becomes "intelligent".

Universal numbers and statistics, are not necessarily all that would be needed in order to meet the exact conditions to form life, at least life as we know it here on Earth.

Cosmologists/astronomers/physicists and a lot of other "scientists" like to quote the incredible number of possibilities and probabilities that "must exist" in the "known universe" that make it just about impossible for life to not exist elsewhere out there. The fail to follow up with the statistics for the creation of life itself. Life is not created automatically once the proper "sun" and properly placed planet, and properly sized planet, come into the picture or into existence. There must exist at least quadrillions of other conditions before life as we know it can come into existence elsewhere.

So, it's quite possible that, we are alone. Although I do hope there are other "siblings" out there.
