When Kṛṣṇa was present on this planet, nobody could control Kṛṣṇa, but He controlled everyone. Nobody could control Kṛṣṇa. So therefore the great saintly persons, even Brahmā, they have decided, that īśvaraḥ paramaḥ kṛṣṇaḥ: (Bs. 5.1) "The Supreme controller is Kṛṣṇa." He controls even Brahmā, ādi-kavaye. In the Śrīmad-Bhāgavatam it is said, tene brahma hṛdā ādi-kavaye (SB 1.1.1). Tene, He instructed Brahmā śabda-brahma, Vedic knowledge, hṛdā, through heart. That is Hṛṣīkeśa. You can argue that "Brahmā was the first creature within this universe. So how he could be instructed by somebody else?" No. The somebody else is always there within the heart, Hṛṣīkeśa. Hṛṣīkeśa means controller. Sarvasya cāham... Kṛṣṇa says in the Bhagavad-gītā, sarvasya, in the fifteenth chapter, sarvasya ca ahaṁ hṛdi sanniviṣṭaḥ: "I am sitting in everyone's heart." Mattaḥ smṛtir jñānam apohanaṁ ca: (BG 15.15) "From Me, one remembers and one forgets also." Forgets also. If you want to forget Kṛṣṇa, so Kṛṣṇa will give you such intelligence that you will forget Him forever. Ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (BG 4.11).
So the atheist class, demon class, they want to forget Kṛṣṇa. So Kṛṣṇa gives him such intelligence that he can speak of atheism so many volumes. But he is getting that intelligence from Kṛṣṇa. Kṛṣṇa gives everyone the chance that "Whatever you want to do, you can do. I will give you intelligence. So if you want to become atheist, then I will give you intelligence how to become first-class atheist, like Hiraṇyakaśipu, Rāvaṇa, Kaṁsa. And if you want to become devotee, then I will give you intelligence also in that way." Buddhi-yogaṁ dadāmi taṁ yena mām upayānti te. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10). Anyone who is engaged in His service with love and affection, teṣām, not all, not all... Because not all, not everyone wants to serve Him. Everyone wants to become God, imitator. Imitation. Therefore they say, "Why Kṛṣṇa shall be alone God? I am God." You are God. That's all right. But you are not the Supreme God. Why you forget that? You may be a God at home of your wife, but when you go to your office, you are not god; your master is god. He directs you to do something; you have to do it.
