Rev,
I would have concur to w/ Perdition that given the number of galaxies in the known, observable universe(not counting the possibility of nearly an infinite # of multiple-universes) (approx 10
11- 10
12 galaxies) with the averaged number of stars in each galaxies (10
11 to 10
12) for a grand total of 10
22-24 stars (that is approx 10,000,000,000,000,000,000,000,000 stars in the known universe). If we averaged that there are 3 planets around each star (some stars have no planets, some have many more than 3) than this would figure to be approx 30
21 planets in the universe. Estimates with the 300+ known extasolar planets we have discovered within the past decade are that nearly half of them could be condusive at some point in the main sequence evolution of the star. Even if we are ultra-conservitive and say only 1/4 of these solar systems have 1 planet that could have at one point in its history have potentially harbored life. Considering that the universe is approx 15 billion years old, the average size of the planet is the size of the earth and with over 2
21 potentially life-habitable planets, is life really unique only to Earth? Or is this just a form of anthropocentrism.
BTW, I went to college near Elizabethton, TN. Very beautiful place to live. My wife and I just spent time up there at a B&B on the other side of the mountains in Boone earlier this year (she's from Hickory, NC).
