If you want actual manuscript written in ancient times, then it is impossible for them to have survived. Either, someone would have made copies. Or someone would have re-attributed something from the same, in a later text, as a paragraph or a citation, using which you can extrapolate what might have been written in the original.

@rohandev1444 I am not sure I understand your Quran and Bible reference here. I was answering to the guy who was asking to show Sanskrit text from ancient times, to which my reply was, it is not physically possible, but that doesn't mean, the content of the text wasn't passed on.
