The Universe is contingent and transient.
The funny thing is all the thoughtless atheists who think they are asking an unanswerable question when they say "Where did God come from?" or "Who made God?", when all the while they believe in an uncreated, eternal Nature. The issue is not whether we believe in something uncreated and self-existent. We all do, in some form.
The issue is what belief is the most parsimonious and avoids pitfalls of logic or violations of natural law. For example, the naturalistic position violates the unity principle, by asserting that the same law of causality that governs everything in the universe somehow fails to hold true for the universe as a whole. By contrast, the creationist position is that natural laws and nature itself were created by a transcendant source that is not subject to the laws He created. Thus the irrationality of asserting something had to make God, because the answer is that the law of cause and effect wasn't operative until God began to create (at which point it implicitly came into being).
And they think they're being pretty clever when they do that, as well.
Not one single person who ever sprang that stupid question on me ever let me answer, either.
The Universal Question has been answered by the computer Deep Thought. It was pondered for so long that by the time it was answered the care takers forgot the question.
Deep Thought’s answer was forty-two. Some argued that 40-2 is actually 38 but there are heretics. The ultimate answer is forty-two.
