@ Lolly there is roughly 4,200 religions in the world. Not everyone believes in the bible. The bible may have all of the answer for you in particular, but not for everyone else who is not rooted in that belief.
Also, not only that, but the bible may not even have all of the right answers for those who believe in the bible. Simply because the bible can be so perplexing, abstract, and bewildering. One simple text can be comprehended in a dozen ways, depending on the reader’s perspective.
Also, the bible is filled with countless stories that defy both physics and science. So regardless of where you stand in the matter, I think that it is reasonably fair to say that life is confusing.
