For all we know, the spontaneous creation of life from inanimate matter is extremely unlikely. Otherwise, it would have happened on earth more then once. And would have already happened in our galaxy's past and we would have aliens all over the place.
But there is a theory that doesn't need an extremely unlikely event: We are part of a simulation. And the guy who runs the simulation manually put in a self replicating molecule to get the whole evolution thing going.
What do you think? Is this a sufficient argument to prove the existence of God?
So, slowly but steady the amount of this molecule increase. Perhaps it needs a million year to conquer the word, but there is no rush because there is no one to compete. Some of the copies are bad, but one of the copies can copy itself in an amazing 5.5 days! (Or perhaps lives for 7.5 days and it has more time to try to do the second another copy.) Now the new version 0.0.0.2 conquers the word! ...
If something like that appears today a bacteria will it in a second, a amoeba will eat the bacteria, some nasty animal will eat the amoeba, and a lot more of eating will happen before the spontaneous generated barely alive molecule has time to do a copy of itself.
The problem with the second spontaneous life creation is that the first spontaneous life creation creature will be so much faster that the second’s creatures will have no chance to survive.
