This is a great topic and I have so many strong beliefs on it. I say beliefs, because I feel like I just know. I never argue about it because to me there is no arguement. Life is not the end and though I know Science is a true and essential part of the universe, there is more than that.
How you said, Ricki, that you just 'know' things, I completely understand that. What I 'know' has nothing to do with what studying religion, society, my parents or anyone else has taught me. It is just intrinsic. Sounds weird, I guess, but that is the way it is for me.
It is such a personal thing, but for me, life is not "the end." It is just not that simple.
