"The Ancient Greeks believed that you could discover hard scientific knowledge about the whole universe by just sitting thinking and talking about it, today we call that "mental mass debating", and insist on having some documented 'facts'."

Not all ancient Greeks. That was Plato's view. But Aristotle said, "Go look. Then think about it. Then go look again." Sounds kinda like basic scientific method to me. There are those who maintain that the rediscovery of Aristotle's writings and his style of thinking were partially responsible for the Renaissance. They most certainly turned on people such as Galileo.
