Creation the Vedic view

Kṛṣṇa is the Source of All Incarnations
(1) "In the beginning the Supreme Lord
assumed, for the creation of the worlds, the form
of the Original Person[: the integrity of the material
realm] composed of the sixteen elements [of
the ten knowing and working senses, the mind and
the five elements] and the cosmic intelligence and
such. (2) Resting in His meditative slumber in that
water, out of the lotus that spread from the lake of
His navel, Brahmā was manifested, the master of
the progenitors in the universe. (3) One believes
the different worlds [as expansions] to be part of
the form of the Fortunate One that constitutes the
excellence of the purest existence. (4) His form
thus seen perfectly has numerous legs, thighs,
arms and faces, with wonderful heads, ears, eyes
and noses, all glowing with garlands and dresses.
(5) This source of the multifarious incarnations is
the imperishable seed from which the plenary portions
and portions thereof, the gods, the human
beings and the animals, originate.

The above text is taken from Shrimad Bhagavatam. In my opinion,it describes the creation theory as subjective matter. What extra knowledge we learn from Atharva Shirsha? Then it requires to go into the objective methodology which is the main expansive extension of knowledge in Vedas.Ganesha is the source of innovation objectively and therefore assumes the wisdom of creation. The iconic visualization is more apt in these circumstances.
