Losing my faith need help?

I've been a Christian all my life, spent almost every Sunday at church and currently have been going to church for the last 2 years every Friday and Sunday. Lately I've been questioning God although I know I shouldn't. It's just I've been told that I'm to take the bible literally. There's so many unanswered questions that I have been asking but my teachers either give complicated answers or avoid the question in general. If we deserve hell in the first place than why do people in third world countries and millions of people around the world never have a chance to know Jesus Christ, they all go to hell, eternal suffering it makes no sense I would think they would rather not be created in the first place than suffer in hell eternally. Also cavemen and primitive people have been proven to be in existence yet Adam and Eve were supposedly the first to be created. What about dinosaurs, and Noah's Ark? Are we suppose to believe that all the animals in the world were put on a ship and saved?
