- The Milky Way contains hundreds of billions of stars, and billions of them are similar to the sun.
- It is highly likely that some of these stars will have planets that are similar to Earth.
- If we assume – via the Copernican principle – that Earth is not particularly special, then intelligent life should also exist on some fraction of these Earth-like planets.
- Some of these intelligent life-forms might develop advanced technology, and even interstellar travel.
- Interstellar travel would take a long time, but as there are many sun-like stars that are billions of years older, there has been plenty of time for such travel to have occurred.
- Given all this, why haven’t we met or seen any trace of aliens? Where is everybody?
# It is not so easy to evolve to high-consciousness 21st Century humans.
# The entire universe focused over the eons to get Planet Earth
(and its humans) to this point.
# The odds of reaching this point are radically longer than
mainstream science assesses.
