However, I have a hard time understanding the connection between those things you list and "... and therefore this may be evidence of a constructed universe."
I just don't see it. For example, things "without concrete explanations" are more easily chalked to our lack of understanding. Or even better, to the idea that there's no "why" to the universe, it just is; we can sometimes understand the "how" to some degree, if at all.
I think some emergent properties like consciousness and others are elegantly hypothesized about in Stephen Jay Gould's "The Panda's Thumb". Some things arise as secondary structures to other things which more readily relate to the environment. Like some hypothesize -- mind you, not interested in whether this specific hypothesis is right or wrong, just an example -- that walking upright/hip posture may have precipitated the evolution of mammalian brain cortex as a side effect!
I don't want to pick on or challenge your every sentence, because I understand this is just opinion and we're all entitled to it. But I really don't see where's the evidence for a constructed universe.
