"Actually, IIRC, the Bible was unique in suggesting a beginning."
Well, not really. God was already there. God existed. God created.
What was God's beginning?
In reality, most creation myths start with a deity on the scene. Few have an explanation about how it got there.
You have to know just where to stop asking questions to believe in a religion!
That goes for science's creation myth. Science just doesn't begin with a deity, it begins simply with matter that *existed*. It doesn't explain how it got there either. *In the beginning there was singularity.....*
So where'd singularity come from? What was holding it together? How long was it like that? If it was being held together, what caused it to expand?
Science can't get past singularity; it has nothing better to offer than religion does with God did it. If anything, at least religion offers a cause, something science can't deal with.
Yeah, who created the Flying Spaghetti Monster?
