DAVID: We agree. Balance is always present. We disagree that it is required for life.

dhw: Different balances of life will always be present so long as life is present. Whatever balance exists at the time enables the survivors to survive. That does not explain why your God had to design and then destroy 99% of species, or why he had to design the weaverbird’s nest, so that humans could appear. And if humans disappeared but bacteria lived on, you would still have your balance “required for life”. Balance explains nothing.

After 3.8 billion years of evolution, balance provided the energy for life to proceed to evolve us.
