One of the most enigmatic questions of philosophy and theology relates to the nature of time. Was the universe created in time, or was it created along with time? Did time exist before creation, or did it come into being with creation?
Most classical theologians affirm that time correlates with creation. That is, before matter was created, time, at least as we know it, did not exist. How one approaches this question of the origin of time is usually bound up with how one understands the nature of time. Some see time not as an objective reality but merely as a category or construction of the mind.
