"You should fear Satan!"

You obviously don't understand atheism.
I am an atheist. I don't believe that the characters in your fictional religious texts are real.

I'm not afraid of Satan, the angel that your all knowing, all powerful god defeated and cast out of heaven, along with a third of all the other angels.

I'm not even afraid of your god.

Neither of those fictional characters elicits any more fear in me than Pennywise the clown from Stephen King's IT.
In fact, Pennywise was a good deal scarier because he was created and written by a much better writer.

So if you want to try and scare me into your religion, you're going to have to do a lot better than Satan.
You're going to have to do a lot better than Pennywise.
They're both fiction.

Personally, I don't think you have the creativity or the writing skills to scare me more than what I consider to be Stephen King's scariest book.

But don't feel bad about your lack of creativity. You gave it up in the blind belief that your god will take care of everything.

Your god and devil don't scare me.
The frightening thing is that the majority of humans actually are scared by such things, and that religious leaders control them through that fear.
I also find it very sad.

I hope to help you see the truth by showing you evidence and showing you how primitive and silly it looks from an atheist's perspective.

Because crying, "Faith!" whenever you see or hear evidence is childishly closing your eyes and putting your fingers in your ears.

Look. Listen. Grow up.
