That figure and the means to calculate is an exercise on probabilities and not even near an estimate.Originally posted by Clyde

95 million to 1 is a bull**** figure. We have no way of calculating a meaningfull figure for the probability of extra-terestrial life because there are FAR too many unknowns.

Actually, the Drake formula is used to value the possibility of life (intelligent or not) in the universe, since the odds of getting 0 are null. Take in mind that you can't put 0 on any of the variables there. The simple fact that we humans exist don't allow for 0.
