Here, we agree. The human brain does not have the information nor the intellectual abilities necessary to "correct creation". Yet we never seem to be able to humble ourselves enough to stop trying. In fact, this is the subject of the story of Eden in the Bible, and is the essence of what is referred to as mankind's "original sin".
Hubris. Human beings thinking they are demi-gods, and that they therefor have the right and the capacity to stand in judgment of all creation. (Presuming unto ourselves the knowledge of 'good and evil'. A knowledge that we
do not, in fact, possess, beyond our own sense of self-preservation.)
We don't need to redesign the world. We simply need to redesign ourselves. And we need to start by practicing some humility.
