So what? If it weren't for the first cave man banging bones against a rock wall and trying to refine the sound by developing dedicated musical instruments there would be no music at all. Similarly it if weren't for that first smelly caveman who learned how to build a shelter in the field out of sticks and mud so he could escape the damp dank cave, architecture would have never moved forward. Personally I’d much rather listen to Metallica and sleep in my warm house than to listen to that caveman bang bones against rocks in his mud hut. Progress is good.
