Why the Universe Couldn't Always Have Existed

 Answering a question on Quora:

If God always existed and did not need to be created, why is not possible that the universe always existed and did not need to be created?

The question needs a two-part answer. First, I want to clarify: For many, establishing the existence of God must precede establishing that God has revealed Himself. A debates over Big Bang cosmology versus various versions of Creationism is a subsequent issue. It can wait. One step at a time.

...why is [it] not possible that the universe always existed and did not need to be created?

Theoretical physicists don’t believe the universe is eternal. They believe it began 13.787±0.020 billion years ago. According to General Relativity, “universe” includes not only mass and energy, but also space-time.

1. Obviously, if the universe began to exist a finite time ago, it could not have always existed.
2. “Always existed” implies an infinite past. If space-time began during the inflationary period as physicists believe it did, then there was no earlier past in which the universe could have existed.
3. Due to increasing entropy, an infinitely old universe would have experienced heat death, long ago. Even if the universe were cyclical or a child universe, entropy would have been preserved through the rebirths or births, so an infinitely old series of cycles would still have produced a dead universe long ago.
4. If the universe began in the infinite past, it would be impossible to traverse an infinite time to get to “now.”
5. It would be impossible to traverse an infinite series of real things or events such as birth-rebirth cycles.

At the minimum, the universe had to begin to exist. This leads to a tangent: Everything that begins to exist has a cause. From the characteristics of the universe and of life, we can infer a number of attributes such as unimaginable power, creative power over space-time that enables spatial and temporal omnipresence, unimaginable levels of intelligence and craftsmanship — attributes of a Creator-God.

If God always existed and did not need to be created….

Again, “always existed” implies an infinite past. That has already been refuted. Theist apologists familiar with cosmology do not say God always existed. They say God had to exist “before” the universe. Since time is an attribute of the universe itself, and the universe had a beginning a finite time ago, God existed outside of time (not “always”).

While God existed outside of time, He also can enter into time. If God created the universe, and time is an attribute of the universe, then God has creative power over time. With such a creative power, God can enter into time, experience it, and interact with His creatures.

In fact, with such creative power, God can enter into space-time as multiple Persons or centers of consciousness. Being Spirit and not matter, the impossibility of two masses existing at the same time and location do not apply. And being timeless and spaceless combines with creative power so that coexisting as three Persons having the same essence (spiritual “substance”) does not create any paradoxes. But the fact of a triune God must be revealed; it cannot be deduced, sensed, or detected.

As with an infinite universe or cycle of universes, an infinite regression of gods creating gods is impossible. If there were a chain of gods creating gods, one of them must be the First Cause. This might make sense causally, but remember, you lack time during which sequences such as need and creation could occur. The idea of God being created is nonsensical in a condition that lacks the dimension of time.

One link in the chain of gods is as far as the evidence and logic permit us to go, and One is enough.
