It's very simple: Many thousands of years ago, we discovered that if we carried on doing the same things, we wouldn't die, because the things that we've done before by definition didn't kill us, and therefore as long as we carry on doing them, we'll be okay, and it's very sensible not to do anything new, because it might kill you.
Tai paprasta: prieš tūkstančius metų supratome, kad jei elgsimės taip, kaip visada, tuomet nemirsime, nes tai, ką darėme prieš tai, mūsų nenužudė, ir jei ir toliau taip gyvensime, viskas bus gerai, ir labai protinga nedaryti nieko naujo, nes tai gali mus nužudyti.
