Man has very great possibilities as a result of his service to the growth of the Cosmic Ray of Creation and the Being of the Earth and its offshoot the Moon, which controls man far more than one would think.
The delay you speak of seems to be a result of the fact that man has lost contact with his higher centers of emotion and intelligence, which are both fully developed and always operating. But, he has psychologically moved into his lower centers, which are un-sychronized due to improper development and they do not operate with their proper energies stealing them mostly from his sex center. Look around.
Man has devolved into Hu-man, i.e., a man or woman by birth but having characteristics of an animal.
This is described in the Bible as the fall of Man in the Garden of Eden, when he chose the Tree of the Knowledge of Good and Evil and was thus barred from partaking of the Tree of Life.
