You may, I do (from 14), but I come from a very religious family and friends and they find great comfort in believing in something other then their own senses. In no way shape or form do I want to argue or dissuade them from their spiritual comfort. In fact, I'll aid them.
My mother died two months ago and I went through the gamut of religious rituals. I had a hard enough time dealing with it while going through a gamut of surreal rituals. Obviously, they gave me no comfort whatsoever, but they keep my father sane, so i'll do whatever it takes, including kissing priests hands if it gives my father comfort.
As a "devout" atheist, I often harshly criticize those who want to criticize other peoples spiritual needs. It's the height of arrogance to assume that one has "progressed" past religion by denigrating others spiritual needs/beliefs. It's another matter if those beliefs by the believers become tools and/or excuses of aggression.
