The Vedantic tradition stretching back more than 5,000 years, asserts that although there is only one God/Source, He can manifest in unlimited forms without restriction, and without any compromise to His status, as the Supreme Lord, known by countless names in different languages that allude to His qualities such as the Almighty, the All-Compassionate, and Krishna, the All Attractive. Lord Krishna explained his appearance, 5000 years ago in the Bhagavad-gita, a chapter in the Mahabharata; the history of India before 3,000 BC.
The Golden Avatar

kaleh prathama-sandhyayam laksmi-kanto bhavisyati
daru-brahma-samipa-sthah sannyasi gaura-vigrahah

In the age of Kali, intelligent persons perform congregational chanting to worship the incarnation of Godhead who constantly sings the holy name of Krishna.

Skanda Purana
