- ekianjo 11y agoHow do you define when Humans started to live, though ? Evolution is not a black and white process, we did not suddenly become humans and stopped being apes. It was probably very progressive and gradual.
- jerf 11y agoAt this scale, a factor of magnitude or two is of little consequence, and odds are, you can get general buy-in within a "factor of magnitude or two" of the number of humans to live from the vast bulk of people who might have sensible opinions.
