How the Big Bang points toward God

The Big Bang theory claims that our Universe is expanding and, as it does so, it is also getting increasingly colder. Naturally, this implies that the Universe had a beginning at some finite point in the past, because if the Universe were eternal then its ongoing expansion would have already resulted in a cold-dead Universe.

This “cosmic beginning” also has very important philosophical implications. The Big Bang implies that the “cosmic beginning” is the genesis of everything, that is, of space, matter and even time. Since nothing existed before this event, the question that naturally arises is, what caused the birth of our universe in the first place?

Logically, whatever causes this beginning cannot be something material, nor something within our space-time, since none of these things existed before. So, the origin of our universe must come from something non-material, not limited by space and must transcend our timeline. Ironically, all these properties are usually ascribed to God which is spirit (non-material), infinite (unconstrained by space) and eternal (time transcended). This is important because one crucial implication of the beginning of our universe, that most people are not aware of, is that, ultimately, it requires an eternal or uncaused cause. Let me explain why. 

What being uncaused means is that it has not been created or, put another way, that it has never begun to exist but has always existed. (i.e., it is eternal). If the reason behind the appearance of our universe is another entity that depends on the existence of a previous one (so it is not self-existed) then one always has to do the regression to the past to explain the present, and do so infinitely, unless, there is an eternal, uncaused entity. Note that this condition is necessary since one cannot look infinitely to the past for an answer because this irremediably means we never get to our actual universe (to get from infinity to now, we require an infinite amount of time). So the mere presence of our universe (which is not eternal, but rather had a beginning) necessarily and logically, requires an eternal cause. 

Everyone alike, atheists and theists, is looking for the uncaused cause, that gave rise to the universe.

This is remarkable, and yet most of the time overlooked

Many people always ask if God created the Universe, then who/what created God? Note that the question itself assumes that God was created. But the God of the Bible is an eternal God by definition, so this question does not apply to him. The God of the Bible has always existed so he does not need a cause (note that “everything that begins to exist needs a cause” according to the principle of causality). Think about it for a moment, it is like asking who created the uncreated God. Nonsense, right?

So the existence of the Christian God is not annulled by the Big Bang but quite the opposite.
