Personally I think it's fine for people to belive in an afterlife, God,
aliens, NA's are as good as TT's etc, as long as they don't try to dictate to others their beliefs and especially harm people who don't agree with them.
This includes shooting, bombing, beating to death with sticks and cutting people heads off all in the name of "***" (insert your fav religion here).
If people need "an answer" especially in times of need like a death etc and it helps them, I think thats fine.
I'm happy not to speculate what will happen to me (apart from the obvious, fire / worms etc) all I know is that I'll be doing the same thing as millions of great people before me.
The interesting thing is that in all probability I'll know before most of you (51 yo)
Best to have as good as time as you can whilst your here (and help other to have one) just in case it's not as good you think it may be when your'e dead.
