“It is not that intelligent human beings did not exist millions of years ago. On the contrary, it is understood that the most intelligent creature, Lord Brahma, was first created. Then Lord Brahma created other saintly sages like Marichi, Bhrigu, Atreya, Vasishtha and Lord Shiva.” (Shrila Prabhupada, Shrimad Bhagavatam, 4.24.73 Purport)
