A Child's Ontological(ish) Argument for God's Existence

It's the metal detectors.
He contains all things,
so they just go crazy when he enters the building.

This is where my mind drifts when I'm driving home from dropping my son off at school:

Peanut butter is the best thing ever.

God is the best thing ever.

Therefore, God is peanut butter.

Peanut butter exists.

Therefore, God exists.

This proof, of course, can be adapted for your favorite food of choice.

Side note: If your favorite food is spaghetti, this also serves to prove the necessary existence of the Flying Spaghetti Monster.
