Pink unicorns are not a hypothesis. They live. All you have to do is really, relaly, really believe it.
But all I did was ask a simple question, that is "if we can postulate na eternal God why not an eternal universe?"
Good night, y'all.
You can postulate anything of course, even Positivism. :) . The next step is the killer where you look for logical consistency, etc. I.e. either show problems in or build the case for your postulate.
In your question, the best logical job for the difference (created, causal vs. uncreated, non-causal) was done by Aquinas. In short, his proof was that there must be something uncausal (theological called "God") behind the string of the causal (the physical universe in your question.)
His proof is neither debunked nor proven to everyone's obvious satisfaction, but is still the meat of very active debate in philosophy. I recommend working through it to those interested in the question.
