The great flood myth, which we can read about in every civilization around the world, quite clearly must have actually taken place. The most likely explanation is that it was an alien civilization, visiting Earth, who genetically modified the homo erectus species already here to serve them and mine them gold; attempting to wipe out the race they had created before departing back to their home planet or somewhere else through the cosmos. The race that was created and survived through the flood are now known as homo sapien, or human beings. We are half alien.
