Itβs still a book. Your belief system is based on your faith that some guy in the past had godβs word spoken to him and they wrote it down lol . Donβt you think a god, especially the way heβs described in religion as all knowing/powerful etc would have given a better sign to latter generations, rather than a book?
Even then, the book is logically flawed. Take godβs characteristics, in practice are they what you see on earth ? Everything points to god being an ego-maniac rather than the 99 names ascribed to him.
The most merciful entity creates a kid in a vegetative state from birth yet the best proof of a better afterlife he can offer them is some words in a book lol sounds crazy to me
