Rig Veda - 129.6. 7 Hymn of creation

 Who truly knows, who can honestly say where.

This universe cam from  
And where it will vanish to at the End?  
Those godlike wise men who claim they know were born long
After the birth of Creation.  
Who then could know where our universe really came from?  
And whoever knows or does not know where Creation came from,  
Only one gazing at its vastness from the very roof of the final Heaven
"Only such a one could possibly know, 
But does even He know? "
