There is no set pattern in chaos. It is not discernable apart from noting that there is a mixture of something indetermined. In another word, there is design if we can deduce pattern, even if something appears to be chaotic. Science finds out patterns and affirms them. In another word, Science affirms creation and points to the Creator.
Science tells of set predictable patterns.
Some patterns are sumed up and represented by equation, formulae and procedure of experiment. True chaos has no meaning, or stability. Currently our world is not set on chaos. We live with certainties daily. There is sunrise and sunset.
