The earth is 5 billion years old, but intelligent life has only existed for about 150,000 years. One reason that intelligent life is unlikely on another planet within our galaxy is that many of the planets in the galaxy cannot exist long enough for intelligent life to evolve. They are located in a congested area where they are destroyed by being bombarded by other larger objects. It takes millions of years with stable environmental conditions for life to evolve into an intelligent life form.

Intelligent life, aka self awareness, has been around for 150,000 years on a planet 5 billion years old. Within a hundred years more we will have to avoid killing this planet off. I suspect there have been millions of planets that have intelligent life get to this stage only to erase themselves. The few that do reach this stage and get through it are either too far away for us to know, or lived millions of years ago and either evolved to some unbelievable state or died out. Or perhaps they are close enough to observe us but take care not to let such undisciplined idiots know about them.
