Carl Sagan said that "extraordinary claims, require extraordinary evidence." In a stunning display of mathematical logic vs common sense, David Spiegel of Princeton University and Edwin Turner from the University of Tokyo have published a paper on arXiv that turns the Drake equation upside using Bayesian reasoning to show that just because we evolved on Earth, doesn’t mean that the same occurrence would necessarily happen elsewhere; "using evidence of our own existence doesn’t show anything" they argue, "other than that we are here."
What Bayesian reasoning overlooks, of course, is the inconvenient fact that there are some one trillion galaxies in the known universe and some 50 billion planets estimated to exist in the Milky Way alone and some 500,000,000 predicted to exist in a habitable zone.
What does ATS think? I know full well that a lot of ATS members believe that they have seen/been contacted by/or are generally aware of the existence of life outside this planet. My question is a little more specific.

They have a very valid argument. So many people use the argument well its pretty dumb to think that we could be the only ones here in the vast universe. Well, think about it. There may be trillions of stars and planets but they are not the perfect distance away from their sun, or the sun is too small or too big etc.
The planet may be too small or too big as well. We may have evolved, YES evolved, you religious twits, simply because our conditions were perfect, nothing more.
The simplest explanation is usually the right one.
