Space Aliens - Where Are They?

When we wonder what life on other planets is like, we must ask if there is life out there. We don't know for certain, but I believe the universe is full of life.

What might it be like?

Scientists have jumped to the wrong conclusions by assuming that, if we just listen for signals, we'll make contact. They listen to the skies for messages from other planets, but have found us alone.

You could buy into the theory that the government is keeping information from us. For the sake of this article, let's forget about aliens supposedly visiting Earth.

Scientists have received no definite signs of transmissions from other planets, radio or otherwise, just space background noise.

If the odds are as high as some believe that the galaxy is populated, why have we detected nothing? What is my answer to the Fermi paradox?

The universe is billions of years old. In all that time, how long has a society on Earth been able to send messages out space? Less than a century. May we be lucky and stay at such a technological level for another ten thousand years. Still, that's a minuscule amount of time for our galaxy and the universe.

Assume that every populated planet gets to a point where they have this kind of technology, and it lasts for ten thousand years. Is it likely that any of their ten thousand year periods would overlap ours? In one billion years, just one fifth the age of our sun, there would be one hundred thousand of these ten millennium periods.

There's a good chance that none of these civilizations would cross over each other at all.

Our own rise to civilization may have been the biggest fluke in human history.

I'm looking at human history as starting when modern humans first came into being upon this planet, about two hundred thousand years ago. They lived as tribal people. Their way of life worked for them, and worked with the rest of the community of life on this planet.

Ten thousand years ago, the agricultural revolution started in the fertile crescent. But the agricultural revolution was not an inevitability. It was strange, because those who started it begin working very hard, rather than hunting, gathering, and perhaps farming just a bit. Previously, they must have had much more leisure time. Full time farming is hard work!

what are the odds the same thing happened elsewhere in the universe?

I think most alien societies are tribal, and not sending out radio signals at all. May they live in peace.
