For thousands of years, Neanderthals barely went anywhere. Humans, however, did things that made no sense, crossing terrain, and water, without knowing what lay ahead. And why do you do that? Is it for glory? For curiosity? It's ridiculous. Foolish, maybe. But it was the Neanderthals who went extinct, not the Humans. Maybe it's only a fool that would perilously journey out to what might not be there. But if you want to solve problems, you don't just solve the ones that are there, you find more.
