Theists basically point to:
(1) Whatever begins has a cause.
(2) The universe began to exist.
(3) Therefore, the universe has a cause.
You might interpet that cause as the creation.
So since God has no beginning you do not believe he had to have a cause. So I will show you how it is possible how the universe need not have had a beginning and indeed could also very well be partially outside of time. Lets take a look, shall we?
While (1) can be challenged on a number of fronts, let me just mention one rebuttal that has been made from physics. Quantum electrodynamics is a fifty-year-old theory of the interactions of electrons and photons that has made successful predictions to accuracies as great as twelve significant figures. Fundamental to that theory is the spontaneous appearance of electron-positron (anti-electron) pairs for brief periods of time, literally out of “nothing.” Thus we have a counter example to statement (1), something that begins without cause.
For this purpose, it should be adequate for me to provide a scenario in which the universe occupies both halves of the time axis. I do not feel compelled to prove that this scenario is true, just show how this is possible within the framework of existing knowledge.
My scenario is provided by inflationary big bang cosmology. Most creations and evolutionists both agree that the big bang is strongly supported by astronomical observations. Inflation remains less firmly established, but remains the only current theory that successfully explains a wide range of observations. Furthermore, the model is falsifiable, and so maintains good scientific credentials. Indeed, with the 1992 COBE observation of a 1/100,000 fluctuation in the temperature of the cosmic microwave background, inflation passed at least one risky falsification test.
Suppose the universe was at some point in time completely empty of matter, radiation, or energy of any type. It was about as nothing as nothing can be, a void. Physicists can still describe the void in terms of general relativity. It is completely flat geometrically, with space and time axes that run from minus infinity to plus infinity. Anything else and matter, radiation, or spacetime curvature would have to exist and this universe would no longer be a void.
