The others left Africa before we did. It appears that there were several waves of emigration from Africa. The earliest may have been the precursors of Homo erectus in Asia. The Denisovans and the Neanderthals seem to have independently evolved from some intermediate form. The exact details of the migrations are still very much a matter of contention. The final emigration out of Africa was of us, Homo Sapiens. That occurred around 50 to 60 thousand years ago.
