Although the clock is a neat invention, it is just that.  To define "one" in the middle of infinity then pretend you can comprehend where "two" is in a universe where everything is relative is a bit ignorant.  We have imprison our minds, our children, our reality from the freedom our universe allows.  This invention is the beginning of our loss to the connection with nature. The illusion of "days" can not alter the truth of the single long night we share. Our species evolution has stalled.  Our ability to sense our own distinct position does not exist. We have not been the free natural born children roaming this earth in a very long long moment.
