I'd wish to go back 6 million years with my evil cabal and our secret headquarters. By the time I reach old age, we;ll have perfected a way to transfer my memories and personality into a supercomputer, I'd then live through an android, giving me near immortality, after about 6 million years with the world under my thumb, I'd be approaced by the wish person and do it all over agian, instead of bring back my cabal, it would be the whole earth. Using the infinite amount of time and energy I would have, I turn the whole universe into my personal domain!
