Does humanity have a reliable future?

“Plato wrote about a catastrophic destruction of Atlantis, which occurred in a day and a night about 11,600 years ago. The Bible vividly describes torrential rains and an immense flood in which most of humanity perished. Native Americans have many rich stories about an enormous cataclysm involving worldwide fires and flooding. Altogether, the myth and folklore of as many as fifty different cultures around the planet tell of similar global devastations, during which humanity went through a trial by fire and flood. Are the cultural legends based on facts, or are they fables?”

Isn’t pre-history fascinating, even if it is worrying?
