Who created Universe

After a year Kabandhi asked the sage:
"Master, who created the universe?"

The sage replied:
"The Lord meditated and brought forth prana
With rayi, the giver of name and form:
Male and female, so that they would bring forth
Innumerable creatures for him.

"Prana is the sun; rayi is the moon.
Matter is solid, matter is subtle;
Rayi therefore is present everywhere.

"The sun gives light and life to all who live,
East and west, north and south, above, below;
It is the prana of the universe."

-Prashna Upanishad
