I've thought about this over the years and have had personal experiences of my own which has formed my opinions on the matter.
First, I think that the purpose for us to be on this planet, at this time, is purely to experience living in a human body in a 3rd dimension reality. Nothing more. It's like we have all chosen an all-inclusive human vacation. Everyday, we get to choose what excursions we partake in and which other humans we interact with. It's all free choice but the free choice can be manipulated by other souls also choosing to have experiences in human bodies. Our scriptures and records are only interpretations of other souls' experiences based on their memories created and recorded by a human mind. You can choose to be manipulated or not, by them. Choice and experience is the purpose of life. Judgement is a choice and an experience. Have it in your 3rd dimension reality if that's what your heart, gut and brain think they need.
