The basic points of the argument, made by physicists Enrico Fermi and Michael H. Hart, are:
The Sun is a typical star, and relatively young.
There are billions of stars in the galaxy that are billions of years older.
Almost surely, some of these stars will have Earth-like planets.[2]
Assuming the Earth is typical, some of these planets may develop intelligent life.
Some of these civilizations may develop interstellar travel, a technology Earth is investigating even now (such as the 100 Year Starship).
Even at the slow pace of currently envisioned interstellar travel, the galaxy can be completely colonized in a few tens of millions of years.
According to this line of thinking, the Earth should already have been colonized, or at least visited. But no convincing evidence of this exists. Furthermore, no confirmed signs of intelligence (see Empirical resolution attempts) elsewhere have yet been spotted in our galaxy or (to the extent it would be detectable) elsewhere in the observable universe. Hence Fermi's question, "Where is everybody?"[3]

my favorite from Fermi is that they may exist, and they may be close by, but they may be too intelligent and we are too dumb to know.
THey compared it to an ant pile and an interstate. Does the ant colony know that the interstate is even there and what it's purpose is? Maybe we are the ant pile?

there are all sorts of things wrong with the fermi paradox.

we are finding out know that intelligent life maybe even harder to come by then originally thought. The drake equation is a bit out dated and a new equation is more up to date with what we now know.
Plate tectonics is thought to be a necessary need for a habital planet...so is a massive giant like Jupiter to occupy the many asteroids and comets with their hefty gravitational fields. Theirs other new thoughts in the paradigm...but those are a few. Still...i'm thinking millions of possible habital planets in our galaxy alone.
still far under what drake proposed
