So I am individual spirit soul. I am conscious. My consciousness is spread all over the body. But my consciousness is not spread over your body. If you are pinched by somebody, I don't feel. Because your consciousness is different from my consciousness. You cannot say that the consciousness is the same in you and me. No. Everyone is individual. Therefore there is another consciousness. That is explained in the Bhagavad-gītā. Kṣetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata (BG 13.3). I am kṣetra-jña, conscious. I know about the pains and pleasures of my body. You know about the pains and pleasures of your body. I do not know about your pains and pleasure. You do not know about my pains and pleasure. Therefore you are individual soul. I am individual soul. But there is another soul, Supersoul. That is Kṛṣṇa. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). That Supersoul is present both in you and in me. Kṣetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata (BG 13.3). Sarva-kṣetreṣu bhārata. In every living entity. Sarva-kṣetreṣu. It is confirmed in the Vedic sūtras, Brahma-sūtra: aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi **. Eko 'py asau racayituṁ jagad-aṇḍa-koṭim (Bs. 5.35). That Supersoul is present within this universe. Because that Supersoul is present within this universe, Kṛṣṇa says, viṣṭabhya aham: "I enter within this world." Ekāṁśena sthito jagat: (BG 10.42) "I do not enter, but My plenary portion, ekāṁśena, Paramātmā..." The Kṣīrodakaśāyī Viṣṇu, He enters. The Garbhodakaśāyī Viṣṇu, He enters within this universe. And the Kṣīrodakaśāyī Viṣṇu enters into everything, even in the atom. Therefore it is working. So that consciousness is there. Because the universal consciousness of Viṣṇu is there, therefore everything within the universe is working so nicely. Not that nature... Nature, you can compare with your body... The material nature is there, but without the soul's presence, the consciousness being there, it will not work.
Therefore as this universe, material cosmic manifestation is working very nicely, you have to accept there is God. You cannot deny.
