"Obviously, our estimates of the number of intelligent species currently residing in our galaxy with technological capacity comparable to or greater than our own varies wildly. That is simply because even our best guesses for each of the pieces in Drake's equation are still just guesses. A number larger than one indicates the number of civilizations currently estimated to exist in the galaxy among its hundreds of billions of stars. The most optimistic number we came up with today is 1000, which is still only 1 per hundred million stars - the proverbial needle in a haystack. The pessimistic numbers (those less than one) suggest that on average, there is no such civilization present in the galaxy. We qualify as one, so this implies that our civilization is a rare and transient phenomenon." From Here.
Drake Equation Calculator Here. I did various values and got answers from below 1 to 80.
Thanks. As Sagan said “Either we are alone or we are not. Either way is amazing” or something to that effect.
