The basic arguments goes like this:
So the question is: If there are so many potential extraterrestrial civilizations, then why haven’t we come in contact with any such civilization at all? That’s the supposed paradox.

The basic arguments goes like this:
- There are about 100 billion sun-like stars in our galaxy, some even older than our Sun.
- Most of these stars ought to have planets around them. That makes for hundreds of billions of planets. Many of them will be potentially habitable.
- Some of those planets can give rise to Life. And some of those can give rise to Intelligent Life too. That amounts to potentially millions of worlds with Intelligent civilizations.
- Some of these civilizations might develop Interstellar travel. Even at a slow place, the galaxy can be colonized in less than a million years!
