Well, if there has never been a time that the Universe has not existed, why would the Scientists speak of the age of the Universe by means of the carbon-14? To speak of age for the Universe is an evidence that there was a time when the Universe had not existed. That's before it was caused to exist. So, Who caused the Universe to exist? You can't escape that. The Universe is composed of matter and matter has not existed for eternity. Why? Because we are parts of the Universe and we all know that we are born, and die. The Universe cannot be eternal if it is composed of temporary elements. The concept of Causality likewise, does not work when nothing is being caused. So, by necessity, the Primal Cause Who could not have been caused became responsible for the existence of the Universe.
