From Jainism, there is no single moment when the earth (Prithvi) or the universe began. The cosmos is considered eternal and without a creator. Here’s the core idea in simple terms:

• The universe (loka) is ajiva and jiva together in a vast, infinite system that has no beginning or end.
• Time moves in cycles (caturvimshati, i.e., great time cycles) with periods of growth and destruction, but the overall cosmos itself is never created or destroyed by a divine act.
• The earth and other parts of the universe come into existence and disappear according to natural cosmic processes within these cycles, not by the will of a god.
• There is no first cause or primordial creator in Jain thought; matter (pudgala) and souls (jiva) are eternal, and their interactions give rise to worlds, including the earth, within the cosmic order.
• This view is shared broadly in Jain cosmology, though Digambara and Śvetāmbara texts may describe certain details (locations, realms, or modes of manifestation) a little differently. The essential point remains: the earth started as part of an eternal, law-governed cosmos rather than from a deliberate act of creation.

If you’d like, I can give a concise quotation from a Jain scripture and explain its exact meaning in both Digambara and Śvetāmbara views.
