It says certain other things too- it says the world map. Vyasa tells the description of the world to blind Dhritharashtra- world has 2 phases as seen from chandramandala. In one phase it is set of peepal leaves and in other it is a rabbit.
Peepal leaves- Americas, Rabbit- Eurasia-Africa-Australia. See it below. It also has descriptions of several geographical sites, regions etc. It can be a myth but need not be either. Just because evidence has been destroyed over time doesn't make it a myth
