The origins of life on earth remains a daunting scientific challenge. The difficulty is in trying to find evidence to infer what chemical reactions took place billions of years ago. There may ultimately be no way to settle the issue, but that does not mean the question cannot be addressed scientifically. (NeuroLogica Blog)
