Assuming for a moment that Quantum Science and Physics theories and models of infinite time have some degree of merit, then we have enough point to question any sense of "beginning" in the context of nothing existing before it. Or, questioning the idea of "creator" in the sense of deity. But with that point, comes the many splinters of discussions on dimension, time, energy, and where laws of the universe start and end.
Because of what we have discovered thus far about our universe, even in observation and including what theories it has given us, it makes sense to suggest we may not be alone in our universe. Even if what we define as life (or intelligent life) is too closed to our context to apply to the possibilities where we assume potential for life based on observed conditions.
Way too much seems to be unknown about our universe to get into something along the lines of inherent or binding force across the universe. If it were an energy field, or some relation of light and/or energy, we would have indication of it enough so to theorize more about it from those observations. Which is to say we do not have enough understanding just yet to know if a universal force of either light, or gravity, or some other factor influences the universe's movements or size or age. There are also too many anomalies out there that defy our context of universal laws. Does not necessarily mean we are on the wrong path of gaining understanding, it may be a simple as we have not seen enough yet to know which direction we should be headed in that exploration of what is around us.
Life after death has too much emotion involved to make something theoretical outside of systems of belief, but there are at least some elements of Quantum Sciences that suggest controls and movements of consciousness apart from how we define life. Perhaps just models and theories as well, but at least we can see potential to think in terms we have not before in answering these questions. Or at least starting to. With the host of possibilities and the more we discover, the more we can see what all consciousnesses can mean outside of our confines of how we define life.
