The math is not bad. You have zillions of chemical reactions around the universe under very wide range of conditions going on for billions of years. It's like playing the lottery. If you do it one time, the odds of winning are very, very tiny. But if you play lotto for billions of years, you are bound to get the prize many times. Abiogenesis is the same thing. I am quite confident that scientists will be playing God some time in the future, and create life out of organic substances.
Yeah but then you have to account the probabilities of that happening under the perfect environmental conditions, then one you have that you have to factor the probability of that single cell organism becoming a multi cell organism under the perfect conditions and you need to have that happen billions of times.
