|“||Grodd certainly knows his history.||”|
History was a science that involved the study of events that happened in the past. This could be the study of humanity's history, or anything else's history. History was constantly being re-written, as further studies about the past revealed new truths not previously realized.
At times, historical facts may have been hard to determine, since certain literary sources may have contained contradictory information, for example, most accounts indicate that Kal-El was sent to Earth already born, in a space ark, while one inexplicable account states that he was sent in a birth matrix, and wasn't born until he was on Earth.
