The same "proof" you have for a God, I have for magic pixie unicorns.
They are invisible, and have always existed since before time. The magic pixie unicorns, here on the MPU, are trickster gods, and they delight in confusing gullible humans.
The MPU created everything, then got bored, so they made people to f**k with for funnies.
MPU are neither good nor evil, they are mischievous and good natured, but they value entertainment higher than human life. They made us as part of their game, so they think of us as pieces not players.
The MPU are strictly good to other MPU, they have a harmonious and loving society.
The MPU tricked Abraham, and have been rolling the Jesus joke forward ever since.
