Who really knows? Who will here proclaim it?
Whence was it produced? Whence is this creation?
The Gods came afterwards, 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 even He does not know.
– Nasadiya Shloka, Rig Veda c.1700 – 1100 BC
