@Shanunoy ask her to explain the meaning of prakrit, it's basically similar to pre , prakirt is term used for lesser evolved language to sanskrit .The earluer forms of Sanskrit are sometimes termed as prakirt .
यत्र स्त्रीणामपि किमपरं जन्मभाषावदेव प्रत्यावासं विलसति वचः संस्कृतं प्राकृतं च
[Kashmir], where the women also speak Sanskrit & Prakrit as native languages and delight in their words.

Prakrit is a class of languages descendant from Sanskrit. There are many Prakrits viz Shauraseni, Gandahari, Pali, Magadhi, Ardh Magadhi, Maharashtri. Sanskrit and prakrit both are indigenous to Bharat. The relation between Sanskrit and Prakrit is discernible in the works of the Kashmiri poet Bilhana twelfth century ce who affirmed that everywhere in his native Himalayan area, the women spoke both Sanskrit and Prakrit with native fluency.
And how come sanskrit be arrived in 609bc when vedas are giving a description of 7k bc old river with exact reference in sankrit shloka
It cannot because Sanskrit is indigenous to Bharatam Janam and is the oldest Indo-e language.
And a pre-buddhist Sanskrit text is not far to seek :
VEDAS
"Yaas Cedam Upasrnvanti Yaas Ca Dooram Paraagataah"
All plants that hear this speech and those that have departed away. RigVeda 10 97 21.
This Mantra from the Rig Veda is direct evidence of its authors awareness of the fact that by the time of the last phase of the Rig Veda tenth MANDAL many plants had already become extinct from the SINDHU SARASVATI region and had receded to the Himalayas or even more distant locations. This MANTRA is direct evidence of the climatic and ecological change taking place during the very period of the RIG VEDA.
The Rig Vedic descriptions of the Northwest BHARAT climate encompass a long period spread over several millennia and the varied shades of environments and climates changing with time transmitted as oral tradition and recollected from the folk memories and edited into the hymns as we get today.
Thus the language of the SHLOKAS is of a bit later time nevertheless the content remained the recollection of northwest Bharat's past covering several thousand years.
There are hundreds of examples of these will mention one of them. In the RIGVEDA when it says "
Vrtrasya Jatharesu Parvatah" this SHLOKA describing the climate is consistent with the hydrology of the dry cold climate of that region during the Late glacial peak occured 11000bce-9500bce (PREMENDRA PRIYADARSHI) when lot of water had been trapped in the glaciers and represents the folk memory of the period of drought and aridity recollected at the time of composition of RIGVEDA at 8000bce to 6000bce easily.
