I don't think time exists. I think we have existence and being, we have contingent beings that are mutable and contingent items such as rocks that wear down but time has no impact on either. Time is just a concept that man invented. If there were no movement we would still have existence and hence for sake of phenomenological talk - time would still exist. My hair turns gray and my skin wrinkles because of the change in my hormones - not time. Often time is used as though it has causative powers. Can someone give me an argument that would refute this statement that time is not real but merely a concept?
