If there wasn't a god, then who the fuck came up with cheesecake?
I think we can all agree that cheesecake is delicious.
Cheesecake is so good, it could be called, "the Essence of Good."
Since we humans are clearly full of sin and incapable of creating anything that is perfect, and cheesecake is perfect, (see above,) then humans didn't create cheesecake.
Then who did?
Fucking god, that's who.
