Do you think that only a supernatural intervention could solve and put an end to all the world's problems?
Or will the supernatural powers-that- be just leave humanity to exterminate ourselves via nuclear weapons, die off from incurable diseases, or pollute ourselves to death...
Are you familiar with the phrase, "Only the strong survive?" That is what will happen to humans. Evolution will take its toll due to various happenings and what is left will be the next generation.
