e a human being, but His activities were unparalleled. From the very moment of His appearance to the moment of His disappearance, every one of His activities is unparalleled in the history of the world, and therefore anyone who knows what we mean by Godhead will accept Kṛṣṇa as the Supreme Personality of Godhead. No one is equal to the Godhead, and no one is greater than Him. That is the import of the familiar saying "God is great."
There are various classes of men in the world who speak of God in different ways, but according to the Vedic literatures and according to the great ācāryas, the authorized persons versed in the knowledge of God in all ages, like ācāryas Śaṅkara, Rāmānuja, Madhva, Viṣṇu Svāmī, Lord Caitanya and all their followers by disciplic succession, all unanimously agree that Kṛṣṇa is the Supreme Personality of Godhead. As far as we, the followers of Vedic civilization, are concerned, we accept the Vedic history of the whole universe, which consists of different planetary systems, called Svargaloka, or the higher planetary system, Martyaloka, or the intermediary planetary system, and Pātālaloka, or the lower planetary system. The modern historians of this earth cannot supply historical evidences of events that occurred before 5,000 years ago, and the anthropologists say that 40,000 years ago Homo sapiens had not appeared on this planet because evolution had not reached that point. But the Vedic histories, such as the Purāṇas and Mahābhārata, relate human histories which extend millions and billions of years into the past.
