The very essence of classical physics was that there were certain immutable laws which the entire universe adhered to, that were adequate to account for everything in the physical universe. For some this supported the atheist view that, there were no inherently mysterious or unpredictable forces, that nature's finely meshed cogs made God redundant.
So to, evolution is invariably touted as being a simple set of rules adequate to account for all life on Earth and so makes God redundant.
As stated, the crucial reason classical physics utterly failed to account for the physical world, was entropy. By simple laws alone, atoms and the universe would collapse into it's simplest state- the physical world requires excruciatingly finely balanced instructions, a blueprint to guide it on specific productive, functional paths with emergent properties.
Evolution is exactly the same, random mutation and natural selection alone utterly fails to account for the living world we see around us, without very specific information guiding life towards specific goals, the simple laws alone would result similarly in the simplest blob of replicators.
And for these instructions to just happen to create a single sentient being among millions , that is capable of appreciating it all.... by pure chance... it's not technically impossible I suppose, but hardly a safe assumption give the staggering improbabilities.
gravity and heliocentric orbits- yes, a perfect example of something once superficially considered simple, immutable, intuitive, yet turned out to be a product of very complex,finely tuned information specific to producing this result
