...our world would look the same as it does now. It wouldn't be some grand utopia, nor would it be some chaotic dystopia. It'd just be full of people stumbling through life trying to get by, same as it is now.

Science, knowledge, cooperation in world betterment, would be progressed about two thousand years.

Despite the fact that the Earth wouldn't be dying, we'd be living on other planets in other solar systems and have our own space ships by now. That thousand years or so known as the Dark Ages cost us alot.

We might posibly be guided by an evolving moral philosophy. "Do not unto another that you would not have him do unto you. Thou needest this law alone. It is the foundation of all the rest" (Confucius, 500 BCE)
