Hello, just to clarify, I
do think that there is probably life elsewhere in the universe, intelligent life even, but it is not certain, or likely,
just because there are billions of planets.
I think that there is life out there mainly based on a leap of faith that...
1. Conditions vary randomly across the universe (big assumption)
2. Amino acids can be formed by commonly occurring reactions (not such a huge assumption, we can make them in reactions on Earth - by firing lightning through certain gases - we don't know how common such situations are across the universe; supposedly quite)
One important thing about probability that everyone forgets when discussing the universe etc, is that you can't 'undo' one result to infer something about the variable.
Some people say stuff like - the chance of the universe developing as it has are 1 in 10248912478012740912784952178918570247209124, therefore - God.
CR had a sig once that was like, chance of 7/7 attacks happening - 1 in 12401278094712047120 therefore, conspiracy.
YOU JUST CAN'T DO THAT.
It's like getting 100 decks of cards, shuffling them, dealing them out and getting some order.
OMG!!! What are the chances of getting that exact order!!! Like 1 in 102193021589125858901258125!!! Must be a set up! We could play for a million years and never get that order again! OMG New World Order ownz teh cards. It makes so much sense now...
Or how about a machine that produces a random number between 0 and 1. What are the chances of getting any specific number? Zero. If you run the machine, will you get out a number? YES.
