What it comes down to is the origin of all origins. The origin beyond the origin of species, beyond the origin of molecules, beyond the big bang, the origin of existance, which simply cant be explained. Because from nothing, comes nothing. So that leaves us with the assumption that "something" was always here, which is equally as hard to grasp. This is where religion comes in. Even the original posters philosophy resembles reincarnation such as in hinduism. Various religions adopot, think up, and fabricate on other religions belifes in order to make that religion more desireable and creditable.

Also, youve already experienced what its like after death. Before you were born.
