What is more reasonable, Creator or chance? (Hint, there is no reason to chance - so why do you continually find reasons from it?)
What were the variables at work? What were the conditions and physical limitations (if there were any) before this universe? Without that information it's impossible to form an informed opinion on the likelihood of either.
When you bring up the question of the variables at work you also bring up the question of whether the present is the key to the past. We look at data available today and assume that what we currently see is an indication of what was all those many years ago that we were not present to. Thus, we INTERPRET the data by what we presently know and what we presently suppose.
You also bring up the possibility of someTHING existing before the universe. You suppose something before the Big Bang, perhaps a multiverse. Energy is dissipating and the universe is supposedly dying a heat death. By positing "before this universe" you presuppose the universe is not the start of time. Are you proposing an infinite time frame?
As for the rest, you seem to be simply stating that order cannot exist without intelligence. I have yet to see any reason to assume this is the case. In an ordered universe with consistent and predictable forces at work it should be expected that we find constants from these we as intelligent beings find reason. The real question is does such a universe necessitate an intelligent creator. Having found no evidence to allow me to conclude either way it remains for me at least an unknown.
You won't find a reason without intelligence. Why do we continue to find reasons, meaning, purpose in a supposedly meaningless universe? Why do we continually find order in a chaotic, mindless, random chance universe? You just ASSUME it is possible. Why would we see the uniformity of nature (laws that govern the universe and without which it would not exist)? How does random chance happenstance sustain anything (laws)? You just ASSUME it must because there is no view other than God that can account for it. You don't like that alternative. It means, if God exists, then you are ACCOUNTABLE to Him. You are not autonomous after all. That is a frightening thought to many, so they rationalize away God as they build their house of cards.
Your real question shows just that, the intelligence of creation. It shows it from the microscopic to the macroscopic, from the small picture to the big - information and intelligence. How do you explain intelligence without an intelligent being? You have no reasonable answers for this, nothing that makes sense. Sense depends on sensible being(s).
Why would you find laws in a random, chaotic, happenstance universe? WHY? There is NO REASON. Yet you continue to find reason in these laws. These formulas express order and thought. Why do we DISCOVER them in a meaningless universe?
Why do we discover information in our DNA, the genetic code? From one end of the spectrum to the other we continually find meaning and purpose. How can something without personhood produce consciousness, intelligence, logic, truth, order? Secularists dogmatically assert that these things can happen without making sense of any of them.
So, of the two possibilities, God can and does make sense of the universe, of being, of life, of morality, of meaning. The universe does not, nor can it do so. You are welcome to such absurdity, but I believe you (generic) act on blind faith. There is no reason to believe otherwise.
