OK, sure. It's true, we don't have enough of an idea of his goals or personality - if such a thing we could even refer to as a personality exists in that blank gray head of his - to guess at things like that. But our timeline seems to suggest that, unless there was some eons-old project he had to finish before we all developed internet access and started swapping cat pictures, it's highly unlikely he was around for that long. (Assuming he's around at all.)

Or maybe he started showing up in 1600s Germany, as some claim. Fine. That's not a huge temporal difference.

I'm more interested in the other question anyway. :D
