Although material part is dominating in our everyday life, one shouldn't forget the mental side of it. Most of us have had questions like "Who am I?", "What am I doing on this planet?", "What is my mission in this life?", etc. While searching "truth" about us on this planet, I have found several interesting sources that cover pretty well questions like these and the most overhelming one is The Urantia Papers.

And The Urantia Papers contains information about the history of Urantia, it's inhabitants, it's creators, and everything that is in any way connected to it. Interesting? You can find answers to many questions that have been unanswered for a long time by looking at places pointed out below.
