You were abducted by aliens and experimented on, you were sent back to earth with the knowledge and ability to solve any problem on earth

Now that I have returned to earth with extreme knowledge and power, I have the ability to solve any problem in the world. I will start with antigravity enabling space travel for all. I will then discover the secret to longevity. I will answer the uncertainties of the world such as how the Pyramids came to be, lost civilizations, nuclear fusion and global warming. Finally, to make my millions, I will reverse male balding.
