Were the universe to be deterministic and not of an intelligent design, then one must posit the universe itself as some prior, highly organized entity that spawns highly organized subsystems. That would beg the question, too, of the first organized universe, or the organizing principle that underlies it.
Some would posit that the ultimate organizing principle that underlies the universe is the Theory of Everything (hence, the name..) but I guess we can't be sure unless and until we discover it!
