MAAF maintains a roster of Atheists in Foxholes, just in case there are any rumors that we don't exist. The next time you hear someone repeat that old myth, just send them here to see how atheists have served honorably in combat - always have, always will.
It's said that there are no atheists in fox holes. I would add... or in a coal mine if you are there for 69 days.
Allow me to explain group dynamics to you, Larry (may I call you Larry? Oh, good.) If I were trapped in a mine, I would try to avoid any divisive discussion. It's not like there's anywhere to go to get away from arguments. If I could not avoid the topic of religion, I would be noncommittal. Again, you can't get away from these people. If things get ugly, and discussions of religion frequently do, there's nowhere to go. I certainly wouldn't point out that god trapped us in the mine in the first place.
Anyway, if pressed with evangelization, I would "accept Jesus Christ as my lord and savior". Quite frankly, trapped in a small place for that long, I'd agree to anything to avoid dissension. I'd agree my mother was a Martian and I'm the reincarnation of a small butterfly that lived for exactly one day in June of 1574. Who cares?
Anyway, I'm not sure what it proves that miners in Chile found a certain type of religion. It certainly doesn't speak to anything I would or would not do, or what any other person would or would not do. Chile is heavily Catholic, so in reality, one type of Christian became another type of Christian.
