Did the Bhagavata Purana describe 7 continents before cartographers?

The Bhagavata Purana describes seven ancient continents called Sapta-Dvipa: Jambu, Plaksha, Salmala, Kusha, Krauncha, Saka, and Pushkara. Each continent is surrounded by unique oceans such as sugarcane juice and milk. These accounts are symbolic of ancient Indian cosmology rather than modern geography.
