Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 33

Sanskrit:

अम्भस्तु यद्रेत उदारवीर्यंसिध्यन्ति जीवन्त्युत वर्धमाना: ।लोकायतोऽथाखिललोकपाला:प्रसीदतां न: स महाविभूति: ॥ ३३ ॥

ITRANS:

ambhas tu yad-reta udāra-vīryaṁsidhyanti jīvanty uta vardhamānāḥlokā yato ’thākhila-loka-pālāḥprasīdatāṁ naḥ sa mahā-vibhūtiḥ

Translation:

The entire cosmic manifestation has emerged from water, and it is because of water that all living entities endure, live and develop. This water is nothing but the semen of the Supreme Personality of Godhead. Therefore, may the Supreme Personality of Godhead, who has such great potency, be pleased with us.

Purport:

Despite the theories of so-called scientists, the vast quantities of water on this planet and on other planets are not created by a mixture of hydrogen and oxygen. Rather, the water is sometimes explained to be the perspiration and sometimes the semen of the Supreme Personality of Godhead. It is from water that all living entities emerge, and because of water they live and grow. If there were no water, all life would cease. Water is the source of life for everyone. Therefore, by the grace of the Supreme Personality of Godhead, we have so much water all over the world.
