How did humans manage to invent, make and manufacture so much compared to that of other animals?
Seriously we, human beings, didn't start with much more than what animals had on this planet like rocks, sticks, grass, water, but how did we manage to make SO much in terms of technology, cars, computers, houses etc etc etc and use materials as such and even make machines that make other machines?
Also, I know that humans are flawed and far from perfect species. And yes we are guilty of pollution and ruining the Earth too.
But how come, those who are moralists and those who criticize humanity by saying how universally "bad" it is, almost NEVER bring up what we have achieved technologically so far as a HUGE argument in FAVOR of humanity and either NEVER reference it or do it briefly, often stating "Yes humans can do this" but animals are better than us for this and that and that we should learn from them etc?
I for one, wonder how we really managed it? How did it start AND also, how come Earth has THIS much materials to make it POSSIBLE, and let's say it was only 5 or so humans left on Earth, could we do it, thanks.
