An Argument Against Intelligent Design

Or at least one by a benevolent, just Creator.

When Nature spawns fish that routinely attack crocodiles, I think its a message to stay the hell out of the water. Intelligent Design's underpinnings have an unstated message that everything was engineered for the benefit of Mankind... but there are and were animals that could squish us by accident. For example, Diprotodon is an extinct species of marsupial, essentially a two tonne wombat with proportionately sized koala claws. The Thylacoleo carnifex (yes, there actually is an animal named "carnifex") was a hundred kilo meat eater that ensured that no early human civilization settled Oz.

To put it succinctly Nature is badass, often terrifying and they didn't throw Christians to lions to watch Christians head butt the lions to death.
