The Short Answer
There have been many different species of "humans" that did coexist at times. This site has a list of some of our relatives that died out along the way, with approximate times of extinction so you can compare and see which ones lived alongside each other, if you like. _URL_0_ Exactly why our line is the only one left is up in the air, but most likely includes the same list of reasons other species die out – someone better comes along and wipes you out, you don't adapt to changing environmental conditions, etc. There's evidence that Neandethals didn't necessarily die off, but merged with homo sapiens at some point as their DNA can be found in modern Europeans and Asians (_URL_1_).
