> Simply because the very basic sounds of sanskrit "Chha" (छ), "Tri" (त्र), "Gya"(ज्ञ), compound sounds, halants and visargas are not present in any script before ....
Wrong Brahmi was capable of representing Sanskrit sounds.

> Simply because much of (Brahman Dharm) Hinduism was invented after the invention of Devanagri script in 11 century.
With this statement you have denied the foundational claim of Buddhism. You have also disowned numerous philosopher of Buddhism. If Sanatan Dharma didn't exist what exactly was being reformed by Buddha?
> Also The classical sanskrit in which all Brahman Text (Hindu text) is written cannot be written in any Indian script before 11th century.
Classical Sanskrit?? Are you claiming Vedas were written in classical Sanskrit? Then Vedic Sanskrit was used for exactly what? Vedic books are transmitted in Vedic Sanskrit which had more sounds than classical Sanskrit. On top of that Vedas are shruti (heard) and they are transmitted orally even to this day.I hope you know about 6 pre- requisite (vedangas)required to read Vedas . First vedanga is Sikhsa which si about correct pronunciati. Chandas comes second and defines the metre of the Vedic hymns.
> Vedas dont prescribe anything in terms of rejecting books, 33% of Rig Veda is only talk fire burning rituals and Indra ...
Which part of veda teaches commandment and asks the followers to be the blind followers? What is wrong in 33% of rigved praising universe and nature. Is regressive but Buddh vandana is progressive?
> You must also address Bhavishya Puran.
Produce the questionable reference first and then we can debate.
On that note you also address the birth based castism and misogyny of Buddhism.
Ariguttara Nikaya (II.35) "beings/ puggalas" are of four categories:
a)tamo tama parayano, of miserable birth and bound for misery
b)tamo jyoti parayano, of miserable birth but bound for happiness
c)joti tama parayano, of happy, good birth but bound for misery

I can produce more references directly from Buddhist text. I challenge to do the same from Vedas and related text.
Regarding your 11th century claim. Brahmin produced Vedas, upvedas, vedangas, upnishads, brahman granths, aranykad, arthshastras,plays and poetry of kalidas,bharthari, numerous astronomy, mathematics books, 6 schools of philosophy, Ramayana, Mahabharata, Bhagwad Gita 11th century onwards when India was attacks from the invaders. I nstead of defending kingdoms, these large projects were started by the ruling class.
