Bry, a part of the human condition is the need to explore and grow our body of knowledge. Without thought and experimentation all current knowledge would soon reach the level of fairytales and legand.
Without science and engineering noone would have time to write plays and watch TV (of course TV wouldn't have been invented - the cathode ray tube is based on a forerunner of particle physics).
We would all be too busy scraping a living by gathering wild berries and catching rabbits.
