Tolong jelaskan mengenai Sajarah dari Kali Gangga dalam bahasa jawa

Sajeroning abad Indo-Aryan wiwitan, Kali Sindu lan Sarasvati minangka kali utama, dudu Kali Gangga. Nanging telu Vedas pungkasan iki katonané mènèhi makna wigati tumraping Kali Gangga, kaya kang disebutaké déning akèh sumber referensi.

mBokmanawa wong "kulon" pisanan kang nyebutaké Kali Gangga iku Megasthenes. Dhèwèké nyebut bola-bali ing naskah karyané Indika:  "India, again, possesses many rivers both large and navigable, which, having their sources in the mountains which stretch along the northern frontier, traverse the level country, and not a few of these, after uniting with each other, fall into the river called the Ganges.  Now this river, which at its source is 30 stadia broad, flows from north to south, and empties its waters into the ocean forming the eastern boundary of the Gangaridai, a nation which possesses a vast force of the largest-sized elephants." (Diodorus II.37.)
