I personally believe we are purely here for progression. Not the progression of a race or species but the progression of us, as one. Every life we live is one that brings us closer to becoming an end goal such as a divine. We learn with every life we live and slowly become better. Throughout our daily lives we live as individuals but we are all one. Hitler and those he slaughtered, Jesus and all his disciples, Gandhi and all that he inspired. I believe we die to come back and live another experience. This is also why newer generations tend to be more open minded and fluent with themselves. We slowly grow until we have lived every possible outcome in the future and the past. Eventually we will be able to remember every life we've lived and realize all we have done, together, apart, and alone all to form one with pure knowledge in the end.
