Before I get into my post, I’d like you very much to check out this post on Ibis’ blog! Another shining example of the abhorrent morals and attitudes on display in the bible.
A good friend (TheGrimm) and I have been discussing the possibility of intelligent life outside of our planet. He made the argument that although most starsPulsars, Neutron stars and other exotics are generally not exactly suitable to the formation of life as we know it have Goldilocks zones around them, few of these stars would actually have planets inside that magical zone. Even fewer of those planets would be suitable to the development of life and for that life to have any appreciable chance of evolving intelligence, the solar system would need some gravitational vacuum cleaners to keep if safe from meteorsIn our own solar system, Jupiter and Saturn fill these roles for us..
All of these together, he argues, make the chances very small indeed. It is all too easy to agree, as it seems statistically almost impossible for all of the right ingredients to come together in the right time and place to form not only a suitable solar system, but for life to get started and have the opportunity to evolve far enough for intelligence to arise. That is, until you consider three counter arguments.
1) We know that as statistically improbable as it is - it has happened AT LEAST ONCE. Here on Earth. We are proof that it may be very, very unlikely but it can and has happened.
2) According to NASA estimates there are somewhere between 200 000 000 000 and 500 000 000 000That’s 200 - 500 billion GALAXIES in the universe with each galaxy having anywhere between 5 and 500 billion stars in them. Even eliminating 99.99% of all of the stars in the universe, we would still be left with BILLIONS of solar systems with the right basic ingredients for life to form and have time to evolve intelligence.
3) All of this assumes that life requires earth-like conditions to arise. Extremophiles have proven us wrong here. There are any number of human-lethal planets that may evolve radically different, but no less intelligent life forms.
Your thoughts appreciated.
