I'm not a religious man, since I am not particularly a man of conviction, but I'm not an irreligious man either! I'm pragmatic, open to ideas, certainly not willing to count myself in or out of the ultimate gamble without all the facts.
So if life turns out to be part of something bigger with ongoing options for my participation, I'll be included as long as no earlier faith is required. If entry is merit-based, I'd be on a stronger footing, with my general good works, pleasant attitude, "do unto others" kind of philosophy. If its "one-in, all in"… so much the better!
On the other hand, if this is all a trick of scientific serendipity with nothing after, then what I'd really want to say at the very end, just before ultimate lights out, is…. "That was awesome….. who do I thank?"
