I really should have said Torah, where I believe mention of the “serpent” refers to God himself. And any other mention in the Tanach thereof.
I believe that “Satan” - call it what you will - undermines monotheism, and still calls man away from himself as an “excuse” for his own sins.
As I mentioned earlier, while I see many examples of God in the universe, there are NONE for “Satan” before Man begins to abstract him from his own mind.
Well, I didn’t mention the serpent...thought it couldn’t have been God, because God doesn’t attempt to mislead nor contradict His own word.
There’s no excuse for sins. We choose daily-—God or the devil. Good or evil. Satan existed long before we ever came along.
There are many, many people who have experienced real supernatural evil...sometimes because they invited it, sometimes not. You don’t have to look far to find them or their accounts. Those people know firsthand that the devil exists.
I won’t go any deeper than that because I suspect you wouldn’t be disposed to believe, but...there it is.
