Who really knows? Who will here proclaim it? Whence was it produced? Whence is this creation? The gods came afterward, with the creation of this universe. Who then knows whence it has arisen?

Whence this creation has arisen—perhaps it formed itself, or perhaps it did not – the one who looks down on it, in the highest heaven, only He knows – or perhaps He does not know.

– Rig Veda 10:129, translation: Wendy Doniger O’Flaherty, Author, Indologist, and Sanskrit Scholar.
