Religion exists to help people cope with the thought of death and answering the question #whathappensafterdeath. All the religions seem to have a different take on this question and requires people to have faith that their religion is the correct one.
Thankfully I stumbled across this book years ago and even though it was written by a random person, I feel the information is actually correct and makes me not afraid of death. This book really resonates with me.
