I think I've already said we don't yet know the means by which it happened.
The sun did it.
I didn't say that. I said that's the source of the engergy.
Okay, 'splain to me how inert matter cooked up the ability to utilize energy so that it could become alive.
I can't. No one can. Not yet.
The Second Law says that if you leave a material system to its own devices, entropy -- heat death -- takes over, not life.
No, that's not it at all, except in a closed system with no external source of energy. We've got the sun. The sun, BB. That's where all life on earth gets its energy. (Except for a few creatures that live in weird undersea hot water vents.)
Well, do you really mind if someone tries a different approach to see what they can turn up? Or do you really expect it will/must be a Darwinist who comes up with that "Eureka!" moment?
Not to be too technical, But if it weren't for the gravitational pull of the sun those undersea vents would have frozen up and died a long time ago, So technically yes even those creatures are getting their energy from the sun.
Life on Europa might be a different story.
