Watch Cosmos, the earth and its cycles haven't been perfect for long and are not even now, the sun gives you cancer... they earth has destroyed itself many times in the past. There were embalances in plant life to bacteria for example that made the atmosphere become toxic with carbon dioxide rich air.
I do 100% agree that the bible portrays god as having analog human thinking. The flood is my go to example, obviously god used miracles... to round up animals, make all that rain and so on. Why would and efficient, loving god DROWN nearly every living human (adults and children), almost every animal on the planet, vegetation and so on, when we could snap his fingers and the wicked people would just cease existing if thats what he was so pissed about. But to be so wasteful and destructive... really????
