As a purely philosophical position, Thomas Aquinas thought so. He argued that the existence of the universe and all that happens in it depended on the causality of God, which entailed an eternal creation and an eternal guidance and support. I have discussed this before in the thread " The First Way Explained. " Professor William Carroll is now discussing the same point in China.

I am sure that Linus2nd knows that I agree with St. Thomas on this point, but I will add by two cents’ worth, in case people find it interesting.
The first thing to clarify is that an “eternal” universe would not be “eternal” in the strict, technical sense of the term. “Eternal” means “without beginning or end of any kind,” and that applies strictly only to God. Even an “eternal” universe would have a kind of beginning, because it is created by God. (Spiritual creatures, such as men and angels, in technical terms, enjoy “aeviterinity:” they have a beginning, but no end.)
So it would be better, in my opinion, to speak of a (hypothetical) universe that is indefinitely extended in time (in particular, into the past). But these are details of terminology.
In any event, to understand why Thomas holds the position that God could create an universe that is indefinitely extended into the past, the key is to understand exactly what he means by
cause.
For Aquinas, something is the
cause of an effect, if the effect
depends on the cause for its existence (whether that “existence” is the very act of being, or some state of being). For Aquinas, every effect depends on a cause (and, frankly, this principle is corroborated by common sense).
They key notion here is
dependence: we can’t speak properly of a cause, if there is no effect that depends on it. In particular, causality cannot be reduced to mere temporal succession: it is not enough to established that event B occurred
after event A, but that event B
depends on event A for its existence.
Now, I should point out that, strictly speaking, a cause is always present and simultaneous with its effect. When I apply a match to a candle, the lit match is the cause of the candle’s being lit, here and now, but
not later, when I have removed the match and blown it out. (The candle still burns, and no longer needs the match in order to be lit.)
This simultaneous action and receiving of action is the kind of phenomenon that truly deserves the name of “cause,” and Aquinas gives it the designation
causa per se. I have thought a lot about how to translate that into English, and for now I have settled on “direct cause.”
On the other hand, there are other phenomena which, when we speak more loosely, we commonly call “causes” that are not the “direct” kind. Aquinas calls them
causae per accidens; I have settled on “circumstantial cause” to convey the idea. For example, the match that I have blown out after lighting the candle is, strictly speaking, not the (direct) cause of the candle flame, at least not anymore. The candle flame no longer depends on it. If we take the term “cause” in a broader sense, however, we can say that the match is a circumstantial cause, since the match no longer actively produces its effect.
Similarly, my mother and father are not the
direct causes of my existence, although they once were, at the moment of my conception. Now, I no longer depend on them for my existence; therefore, they are (in the technical sense) circumstantial causes.
The difference between direct and circumstantial causes can also be seen by applying the maxim
sublata causa, tollitur effectus: if you take away the cause, you take away the effect. The maxim applies only to
direct causes. (Unless I strike the match and hold it to the wick, I can’t light the candle; if my parents had died, or had never married, at the time of my conception, I would not exist either.)
In the case of circumstantial causes, however, the maxim does not apply. Now that I exist, if my parents were to die, or to separate, then I would not by that fact cease to exist. Once the candle is lit, it will keep on burning even when I remove the match and blow it out.
So the key thing to take home from this is that events that follow earlier events in time
do not depend on the earlier events for their existence. The earlier events are merely
circumstantial causes.
God is a
direct cause (indeed the principle direct cause) of all His creatures. Moreover, God could easily create an infinitude of creatures, since His power is infinite. Because successive events do not depend on
each other but rather on their
direct causes, it follows that God could create (i.e., be the principle direct cause of) an infinitude of events stretching back indefinitely into the past. And this would precisely fit the description of our hypothetical “eternal” universe.
