1. I'd cease all life on earth. Except animals, plants, bacteria.
2. I'd recreate smarter and more capable humans who won't simply mess up the awesome world that I made for them by burning crap and making things unpleasant for the entire world. This includes war.
3. Then, my super-advanced humans would discover space flight relatively shortly after their creation. They'd discover new planets and terraform them so that they are liveable. That way, humans can't die out.
4. After that, I'd make my race be technologically well-equipped with awesome space missiles that will fend off any weird alien species.
5. Then, I'd create a nice vacation home in France or something, so I can rest in my awesome world.
