Ok folks, since this topic is almost totally void of hope and lacking in temporal understanding, I'll break it down for you, "god warrior" style!! (would you expect anything less?)
Long ago, in a galaxy far, far away..there was God. God had hundreds of billions of children and they had learned all they could throughout the eternities they lived. God wanted them to have more so he created a world to go down to, to take up and learn how to use a physical body. He gave us free agency to choose for ourselves happiness or misery. While down here, we would not remember all that we learned before because it would not be an accurate or true test. We were given many hints and clues like living prophets, writings of dead prophets, revelation, the Holy Ghost, etc. But along with us is 1/3rd of his children who rebelled against the initial idea of coming to this earth to freely choose our path...this 1/3rd of the host of heaven are on this earth trying to pull us towards misery and ultimately away from our Heavenly Father.
The purpose of this life is to gain a physical body, be tried and tested, find "the way" back to his presense where we can continue in our eternal growth. Building families here and in the here-after is our goal as well as that is where the joy is.
..well, that's not ALL there is to this life... capping bases and raping uncaps is also part of it.
