Auto tuning desiccation resistance in skin was the hardest problem that evolution solved, harder than eyes, harder than lungs, which in retrospect were easy in comparison

We've moved past "believing in evolution".
We've moved past "Demonstrating evolution with repeatable scientific experiment".
We've even moved past putting that evolution into an until(convergence){ do_evolution(); } loop and creating life.
We are at the step of using digital evolution to create life in the same way the simulation made life in the universe, but at faster speeds, because we have control of that temporal slider, and we can dismiss all the irrelevant details.
And so gentlemen, we can boast that we have a proof of evolution in the same way we have a proof for Gravity. You can quibble about the nature of the wave form collapse retrograde in time through the higgs and philanthropica mechanism, but now you're just arguing over the unknown details of how evolution itself, was created into existence by, wait for it, the intelligent designer, the intelligent creator of the simulation.
FUCK. Back at square one, Evolution is a fucking side quest.
