OK, so, maybe we have been thinking about Jeff all wrong. I just got this crazy thought. The "real" picture looks like it was edited, right? Like with Photoshop. Well... Maybe it is. But maybe its still real. And the story. Who's the author? No one knows right? What if Jeff made the story. What if he was the one to make the story. If nobody knows the author, it makes sense for Jeff to have wrote it.
And maybe Jeff doesn't even look like that. What if the picture is him, but like I said, edited. What if Jeff took a picture of himself, and made himself look like that.
And what if the whole "he cut a smile and burned his eyelids off" was just something he made up? I think he is just a normal person but has edited himself to make people fear him more.
So to sum it up, Jeff could most defiantly be real. But not in the way we see him. All my evidence proves he can be real.
