my response to that question is that begin building faith in the Creator in your heart. the foundation for faith is a relationship with God, hot a relationship with a book. ask God for faith,and He will provide. but not faith in words that may or may not have been correctly copied or may or may not have been fiddled with, faith in the real God living in your heart. if that happens these others questions begin to answer themselves.
faith is not easy, but it is fun and it is an adventure and it is part of the reason we are all here onthis planet. it is easy to believe in God when you are face to face with Him, but what about when you are trapped in a body, surrounded by evil and doubt and despair?
but God never leaves us nor forsakes us, He is always with us and is always willing to draw claose to you if you are willing to draw close to Him.
