What about deep underwater vents, where sunlight can't reach, let alone UV radiation? The assumed absence of oxygen is only one of the problems with the life-from-rocks guesswork. You see, Miller's experiments proved that life cannot arise by itself, not even with human help.
Miller used ammonia gas. Perhaps there is an ammonia gas factory at the sea bottom? Ninety-eight percent of Miller's results were poisionous to life (tar and carboxylic acid).
Miller's best results turned out two kinds of amino acids. It takes 20 to make life.
Miller's acids bonded with tar.
Half of the amino acids were right handed. Life needs left handed ones.
The smallest proteins have 70 amino acids- all left handed. All 70 need to be in a precise order.
There are more problems. If "science" can't even get close under ideal conditions, the chance of an accidental creation is unthinkable.
What you guys really need to reproduce in the laboratory is something from nothing as in the BB when nothing exploded and produced everything in this universe.

Not only that, he had to cheat and separate the amino acids he did produce, lest they be destroyed if left in their natural surroundings. No doubt there was a laboratory near the first living cell that arose out of dead matter, so it could be separated from its environment, lest it die.
BTW, if Miller had been succesful, he would've proved an INTELLIGENT DESIGNER can CREATE life. That's what we've been saying all along.
