Dravyk,
I thought someone else would! It's called the Drake Equation. It's really quite simple. Even a child might think of it.
The problem for me is the equation is useless because of terms like
"% of planets where live will develop"
and
"% of planets with life that develop intelligence"
What to plug in? Maybe the odds of those multiply 1 in a trillion or something. In fact, here we are! Really, I think it quite silly to think that maybe 10% of planets with life evolve "intelligence". It should be a very small number. There have been billions of species on earth and that we are here is just plain lucky. Maybe 1 in a billion species. The history of life on earth is the history of bacteria. Life doesn't have to be smarter than you. It just has to be capable of eating you.
