The argument from irreducible complexity. Doesn't work. Discard you Bible in the nonsense basket where it belongs. Lots of things don't have answers. Supposing a God might suffice for some but hardly constitutes an answer.
Yes, the Bible could be written by Man to control Man. It has some good messages in there - better than some other "religious works" perhaps. I am not really an expert on the matter...
But forget about the Bible. It's not my book either. The last time I read it was decades ago.
What's the difference between a God that created the Universe and a Universe that created itself? Not much really. They are both fantastical concepts that require a leap of imagination. I would argue that a greater leap of imagination is required to reason that it all somehow happened on its own without a Creator. That's actually a more farfetched scenario and more implausible. Perhaps the Universe is the Creator?
As far as I am concerned, the Universe is extremely fine-tuned to such an extent that it could not accidentally have developed without some intervening power. Most scientists are in agreement with this.
I am curious though what is the source of the angst atheists display when it comes to the thought of a Creator being responsible for the Universe's existence. What is so threatening about that idea? Humans created the dog breeds. So in a very primitive way, we are also Creators. Eventually, we'll have AI machines that can really think for themselves. Humans will be their Creators. So why is it so difficult for atheists to consider that we might also have been created? It seems to me atheists are almost revulsed by this idea. Does it frighten them?
