The only way to get humanity on track is to do the following:
1. Kill everyone
2. Keep the babies
3. Manage to erase any way for the babies to tell there was something else before them and that
I'm the villain 


4. Indoctrinate the babies in the right way. (I know what's the right way, if you don't believe me, I'll kill you)
5. The babies have kids in the future and those kids will learn the way of the world naturally
6. Utopia and 5 million years of evolution in a couple of dozen years
7. Everyone, clap.
8. In case it doesn't work, repeat until it does.
This is a joke, more or less.
