The universe does things for a reason, I suspect a correction was needed, but only the infinite knowledge source knows for sure. Humanity is headed somewhere good. Humans are much more awakened than they were 5,000 years ago, each century is better than the one before it.
These are exciting times we live in, enjoy the ride!
