Why do religionists believe in an afterlife?
The ancient Egyptians believed that a person had to earn the right to enter the afterlife.
The ancient Egyptian obsession with the afterlife is also quite intriguing, filled with magical amulets like the Ankh and the scarab.
The overwhelming theme from the Christian side of the debate is that actual life on earth is brief, but the afterlife in the Kingdom of Heaven is eternal.
They point out that ancient Egyptians did believe in a transformation in the afterlife, but they believed the transformation was into another world, not this one.
