Here is a huge range for my thinking, and some repetition to ponder. Will we humans bounce up and down, end our civilization and come back after millions of decades? It is perhaps as likely as continuing to grow and improve forever. We do not want to think about decline or extinction, yet we know these things happen. What about consciousness and reason, intelligence and their ilk? Will this go as quickly as it arrived, will nature tire of this plaything? What has been its value in the long scheme? As flowers and bees change each for the other, is thinking and its development merely a toy for the oversized heads of humans? Can nature develop and thrive without calling upon brains?
