It’s probably a matter of when and how, not if, we humans will meet our doom
The species Homo sapiens evolved some 300,000 years ago and has come to dominate Earth unlike any species that came before. But how long can humans last?
Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state.
But a billion years is a long time. One billion years ago life on Earth consisted of microbes. Multicellular life didn’t make its debut until about 600 million years ago, when sponges proliferated.
