Prehistoric=before recorded history
The prehistoric era is the time when dinosaurs ruled the earth. Prehistoric also refers to time before time and history started to be recorded.

A pre-historic beast is an animal that was gone long before our time. Pre-history means before written history.
It is known as the prehistoric period because it was the time in which there was no history recorded, because a system of writing did not exist yet. Hence the word PRE-historic, which inevitably means BEFORE history.
"Prehistoric" means "before written history", so if there was any astronomy at that time, we won't know the exact year.
Prehistoric time is time before history.
