Mankind has always been a wanderer. He wanders through time and through space, somewhat aimlessly. And the reason is that he is totally unaware of who he is. He does not know what his purpose is on the earth. He does not understand the nature of God, nor is he aware of the presence of God. And so he suffers needlessly, and continues reaching out; always reaching to grasp something that ultimately appears as nothing more than a mirage.
