Most people feel they came here with a mission something they like to do that is going to make a difference and perhaps save humanity. For some it is just a little something that sits in there self-conscious but for others it is all they can focus on and nothing else matters.
Humanity is a biogenetic consciousness experiment set in linear time to study emotions. It had a beginning and it has an end. The mission is to figure out the nature of reality as a consciousness simulation that had a beginning and is about to end.
