This goes to prove that Legends are not figments of imagination and that we can not dismiss anything as a Myth as we can not prove it for we might be looking at the appropriate place. Our stubborn refusal to believe anything which we can not establish ourselves . We forget that our vision, capabilities are imperfect. There could have been better people and higher civilizations in the past. Please remember that the Mind will not conceive anything that is not true and can be perceived.
