If you give me a function which returns a value which is proportional to how close a set of words is to the complete Shakespeare, I can write you a genetic algorithm which will generate them from a starting random value very quickly.
Richard Dawkins did something very much like that, with, if memory serves, a few lines of Shakespeare.
He also demonstrated a very nifty “random” function that generated patterns very similar to real-world spiderwebs, demonstrating how “optimization routines” in computers closely mimic real-world optimization. (Spiders that are wasteful of silk are at a competitive disadvantage with respect to those that don’t.)
These kinds of computer sims parallel the real world, and are suggestive of how reality works. They may not prove anything by themselves, but they help point the way to the truth.
OP’s assertion that a “God” created the Universe is far more ridiculous than the idea that the Universe came to be out of nothing.
OP is simply introducing a completely unnecessary middleman.
Why is the idea that an omnipotent deity just came into being and created the universe any more valid than the idea that the idea that the universe just came into being?
Again, OP is just talking about a wholly unnecessary step. The Universe just suddenly appearing is far less unlikely than a deity suddenly appearing and deciding to create a universe and having the ability to do so.
