You failed immediately. A doctrine is a principle, theory, or codification of beliefs taught and accepted by a particular group. It serves as a foundational set of guidelines or accepted truths in various fields. Boy, you blew this one!
But, how do you know there is a God? By your misunderstanding of doctrine, you are implying your own doctrine here. You are inviting me to find God without any clues, information, facts or anything about your mysterious god. In fact, your god is much like the god of atheist science.
As far as your assertions, they are all proven now to be false assertions. There is no way a 24 uneducated young man could write such a complexed book with many personalities with different writing styles in 65 days. The complexity of civilizations in the Book of Mormon without computers would be impossible.

As far as tithing, plural marriages, priesthood garments (religious) and temples are very much Biblical. Nothing made up.
As far as a planet we get? There is no doctrine in our Church about this. Who told you this? We do believe as the Bible teaches that there are 3 degrees of Glory in Heaven that we will obtain in the resurrection based on our faith in Christ. The Celestial glory is the highest and the Bible says Christ said we can be heirs of God's kingdom. Joint heirs in fact. In this glory, it is said that we will continue to have increase in our joy (our posterity). The Bible also teaches that we are already God's in embryo, children of our Heavenly Father. Logic tells us that we will have to have our own realms for our eternal families. I'm sorry that you will be a lone person in the hereafter. Lonely. Nothing to look forward to and have a reason for your current existence.
