Want to feel sadder? Humanity has existed on Earth in its current form for about 200,000 years.
We’ve only had civilization for about 10,000.
That means humans spent about 180,000 years throwing rocks, sticks, and presumably feces at each other in the dirt before we entertained the idea of working together for mutual benefit. With all of our present senses and capacities at our disposal.
Just incase anyone ever wonders why it’s so difficult for humanity to do what’s best for itself. We only do what’s in our best interests after we’ve fully exhausted all the bad options several times over.
