The temporary manifestations and varieties within this material world are simply creations of material nature under various circumstances: prakṛteḥ kriyamāṇa-ni guṇaiḥ karmāṇi sarvaśaḥ. The actions and reactions carried out by the material nature are sometimes accepted as our scientific inventions; therefore we want to take credit for them and defy the existence of God. This is described in Bhagavad-gītā (3.27), ahaṅkāra-vimūḍhātmā kartāham iti manyate: due to being covered by the illusory external energy, the living entity tries to take credit for the differentiated creations within the material world. Actually all these are being created automatically by the material force set in motion by the energy of the Supreme Personality of Godhead. Therefore the ultimate cause is the Supreme Person. As stated in Brahma-saṁhitā:

He is the cause of all causes, the ultimate cause. In this regard Śrīla Madhvācārya says: evaṁ sarvaṁ tathā prakṛtvayai kalpitaṁ viṣṇor anyat. evaṁ prakṛtyādhāraḥ svayam ananyādhāro viṣṇur eva ataḥ sarva-śabdāś ca tasminn eva. Actually the original cause is Lord Viṣṇu, but out of ignorance people think that matter is the cause of everything.Things are contemplated on the ephemeral or external platform, but actually this is not the truth. The actual protector and shelter of everyone is Brahman, the Supreme, not the king.The actual protectress is the material nature, but Viṣṇu is her Lord. He is the Lord of everything. Lord Janārdana is the director both externally and internally. He is the cause of the function of words and what is expressed in all sound.Lord Viṣṇu is the resting place of the entire creation: brahmaṇo hi pratiṣṭhāham (Bg. 14.27). On Brahman, everything is resting. All the universes are resting on the brahmajyoti, and all the planets are resting on the universal atmosphere. In each and every planet there are oceans, hills, states and kingdoms, and each planet is giving shelter to so many living entities. They are all standing on the earth of feet and legs, torso and shoulders, but actually everything is resting ultimately on the potencies of the Supreme Personality of Godhead. Therefore He is known ultimately as sarva-kāraṇa-kāraṇam [Bs. 5.1] , the cause of all causes.
