Once you see that evolution is like the laziest worker ever that wants to do nothing all day but needs the money, and natural selection as the boss that doesn’t give a shit and just gives him tasks and only cares if they are done. You will understand why things are the way they are.

“Why is the mop so moldy and disgusting?” Well because natural selection told evolution to mop the floors every day but never said to clean the mop, and the cleaning products are good enough to clean even when the mop is moldy, so there is no need to care about the moldiness of the mop.
