 Today we know that the universe was a joint entity and the big bank separated everything, but Prophet Muhammad told us this 1400 years ago and being so correct would definitely not be but a higher power. As a former atheist, I have become a much better person than I was. I believed in capital punishment for murderers, but Islam put me that we are all sinners and we have no right to judge people and the best judge is only God. His entire case is that Muhammad knew things when he didn't know them, that he couldn't have known without God, which hasn't been demonstrated, that he's personally a better person with regard to capital punishment. I'm thrilled and happy, but that doesn't tell us anything at all about whether or not Islam is true. That which can be asserted without evidence can be rejected without evidence and no, it's not just the case that can only come from God.
