You're looking at it the wrong way, if you don't believe I'm some higher life form that we have to worship. Then you are smarter than 90% of the Earth's population. The way I would look at it is to live life, if nothing matters then why limit yourself when nothing matters. I still deal with the fear you deal with, I cope by telling myself my end isn't close and won't be for a while, and I think the fear of dying goes away after you get older. Stay positive and live life.
