I have a theory that saitama gained his powers from being to exposed to some radiation or the like. If you remember he lives in the evacuated part of city z. Thats where all the monsters are said to come from. Could it be that theres some sort of other worldy power there mutating things into monsters and saitama is one of them? I would say he had to have already had some innate ability that was boosted to the extreme from being exposed to something. Theres an event that is eluded to that occurred in city z that they are never specific about. I think it has something to do with that.
