I'm an agnostic........I'm not arrogant enough to say for sure HE/SHE does or does not exist, truth is, I don't know.

I do have a good way of getting rid of Jehovah's Witnesses from the doorstep.
Be polite, listen to their chat then say , all preacher like, "Yes but you're all heathen protestants, you're going to rot in eternal hellfire and damnation, come inside, have a cup of tea and let me tell you all about it". Trust me, they'll be up your path and out the gate like sh1t off a shovel.
