Even as we renew our concern and disgust with terrorism, we tend to forget the ultimate destructive power on earth, namely errorism. Against stupidity, the very Gods themselves contend in vain.
Let's examine for a moment the Neandertahal spear and its evolutionary effect on errorism. If we believe in evolution, it must hold true that everything has improved since the time of the Neanderthals which means everything that they were doing was essentially a daft idea or at best a mediocre idea inanely executed.
For several examples , I don't want to imagine how many Neanderthals set themselves or their best friend or family on fire while discovering what fire is, how many Neanderthals drowned while discovering what water is, how many Neanderthals fell to their death finding out what a cliff is, how many Neanderthals choked to death while discovering the difference between rocks and bananas, how many Neanderthal lungs were punctured before the discovery that bones shouldn't be eaten after the meat is devoured or how many Neanderthals were trampled while finding out what a herd of wooly mammoths is.
Furthermore, Neanderthals characteristically failed to learn from their own mistakes. One Neanderthal would watch his friend be trampled by a herd of mammoths and then walk right up and get trampled himself in exactly the same spot in the same fashion by the exact same herd.
Can you imagine the Neanderthal spear? A heavy stick (impossible to throw more than twenty feet) with a dull rock loosely attached to one end and a Neanderthal's filthy grip attached to the other. Can you imagine a Neanderthal sneaking up on a saber tooth tiger ( or even a snaggle toothed tiger) with this instrument, getting within twenty feet (with the tiger wildly aware of Neanderthal's stumbling presence and amazed that this form of supper is stupid enough to be coming towrds him instead of running away). Then the Neanderthal would hurl his pathetic "weapon" that didn't work to do anything other than to irritate the tiger and add a measure of ill natured ferocity and rage to the savagery of the tiger's task of feeding itself. How many Neanderthals were torn limb from limb after such a disastrous, slapstick, half-witted sequence. How many more were devoured the next day after watching the first mutilation, failing to learn from it, and repeating the same farce after reinventing the harmless, colappsible, pointless spear.
Deep within our DNA code, the fenetic compulsion towards errorism keeps driving us relentlessly forward causing such phenomena as the ongoing and ever popular reinvention of the square wheel as well as the current editions of the United States Congress and the election of Donald Trump
In these difficult times, we have nothing to fear but our own specific stupidity, amusing and disastrous as it often is, was and always will be.
