Yes and no (say my religious friends).

Yes, he did "invent" it. But it was thoroughly harmless in the Garden of Eden. Original Sin (humans and Satan) screwed up the world and introduced evil right up and down the line.

There is disagreement about whether the Fall is a factual story or a symbolic one.
