This seems so odd to me, I never found them to be all that hard to manage. I had a few witnesses by last week. I opened the door, greeted ect and one of em asked me "If you could ask god one thing, what would it be?"

I chuckled and said "Nothing."

"Why not?" He asked.

With another chuckle and probably a shitty smirk on my face "Because sir, God does not exist, have a nice day." They both changed their body language from regarding me to 'ah well' and I closed the door to no further comment.

I do seem to get a visit every six months to a year, but they aren't very pushy. Sometimes we chat for a few minutes sometimes I tell em to buzz off.

I did invite them into my house many many years ago. It was all ashtrays, cigarette buts, dirty glasses and empty beer bottles. They were wicked uncomfortable. I told them that mankind's ecological niche was to be the creature that pushed earth life into the stars, and that this wasn't a religious function but a natural biological one. They would prattle on for a bit and I would say "great, but what's really important about men is that we can spread life to other planets. I got them to admit that spreading life to other planets was pretty interesting. They seemed pretty eager to leave after a good half an hour and never came back to that address.
