It depends on the craftier of said apocalypse. Some can begin as an army or government experiment gone wrong. Sometimes it can be extraterrestrial, and hitch a ride or meteorites and such. It can also be a human/disease mutation. Many times the writers leave the cause ambiguous leaving the reader to interpret the cause. It just all depends.
