Well if u really want to understand the Bible i would love to suggest you to start from Matthew to revelation then onwards you can learn genesis. If u can grasp the meaning in the New testaments then you can surely understand. for example you wont be able to understand the book of levitecus unless you have a proper concept being a daughter of god..Til then keep reading as fellow christian we are all here to help if we got extra time though. Be blessed in God's grace

Reading the bible is more about faith and beliefs. Reading it like a history book it doesnt worth much like a piece of history from the past. If u got the whole time in the world to read the whole Bible then u can read the whole Bible. But still i would like to suggest u to start reading from the Newtestament i.e.from matthew onwards. Its easier this way plus u can understand it more clearly. After you finish reading it and strengthenen your basics and faith then start fr proverbs then to genesis.
Well if you got some problems the best way to make you understand it by contacting your own church pastor otherwise your friend online or offline whom you think they r best at it.
