There was a beginning to creation. What that implies is that something outside of our universe started our universe, hence a creation.
That assumes there was a "creation" at all. For a creation to have occurred, something had to have come from nothing (
ex nihilo), so we are now faced with a different problem in explaining how that is possible. In terms of science, it is not.
So we are left with two possibilities: that which we call the 'created universe' is actually an illusion, not requiring that anything pre-exist for the something to come into being, or that there was no "creation" at all; that is to say, that what we call the universe has always existed, except that it has always existed in one of two phases: on and off. When the universe is switched "on", it appears to have been "created", when, in fact, it is only being
manifested in that moment. When it is in the "off" phase, it is unmanifested,
but it is still there, just as a light bulb, though off, is still there. All that is required is for the switch to be flipped.
If it is a manifested apparition, whose appearance is so real that we think it to be real, the problem lies not with the universe, but with how we see it, and how we see it is via of a mind so conditioned that we are not aware that it is conditioned.
Even if a creation occurred, it does not mean there was an external creator-god responsible for its coming into being; the creative force could very well have come from
within, unfolding as a flower unfolds. If that is the case, then the universe is the creative force itself manifesting itself as the universe
*, and that is an entirely different ball game. According to the Hindus, the godhead is playing a cosmic game of hide and seek, in which he is hiding within all of the various manifestations of his "creation". The reason we don't see it that way is because we are part of the game as well. In other words:
"That which you are seeking is what is causing you to to seek".
* "The universe is the Absolute seen through the glass of time, space, and causation. Time, space, and causation are like the glass through which the Absolute is seen, and when It is seen on the lower side, It appears as the Universe. So not only is the Universe apparitional, it's the Absolute seen through time and space, and that allows us to understand why the physics of the Universe takes the form that we see."
