@Leadfoot,
To put it in perspective.
Chance of winning Powerball Lottery: 1 in 292,201,338
Chance of life arising by chance: 1 in 4^300 (remember, this is 4 multiplied by itself 300 times, with each result 4 times the previous. It only taks 4^4 to make a triple digit number. This is a number so big that most calculators will not display it, but I used a large number calculator).
