Which is Normal? Simplicity? or Complexity?
Humans have a preconceived notion that nature aught to be simple and when they discover complexity, the feel compelled to find some special explanation for it (e.g. by postulating a magic deity). But there is no priori reason that the universe has to be simple; it is just, for the most part, to the limited human mind, in the tiny part of space-time we live in, it appears to be comprehensible. So we presume simplicity must be the default.
You could equally well presume that the natural state of things is a complicated mess and whenever you find elegant simplicity, it demands a special explanation. Einstein was gobsmacked at how mathematically elegant (mathematician-speak for simple) the universe appeared to be. As he said The most incomprehensible thing about the world is that it is comprehensible.
Further, the very notions of simplicity and complexity are relative to the powers of the human mind to comprehend. It is like King Henry defining the yard as the distance from his nose to his thumb. What a conceited and provincial yardstick to use the powers of a primate brain as the only measure the complexity for the cosmos!~ Roedy (1948-02-04 age:70)
