If you want to find out the Historical Authenticity of a book/scripture then you have to delve into its contents.....
True.
No-one can go back in time and confirm History....so the only option is to logically and scientifically analyse old remains....
Incorrect, for two reasons:
History is evaluated in the light of historical evidence, that consists of two types reference material, primary and secondary. These are largely written records, although epigraphical records and archaeological records are used where available.
History starts with Written records of a people, an ethnic group, a language group or a religious group, or a political entity, kingdom or city-state.
Proto-history starts when a people do not have history, but other cultures around it have. The proto-history of the Hioung Nu started with their mention in Chinese records. This also refers to the period between the coming of literacy and the writings of the first historians. Finally, this refers to situations where oral traditions exist but written traditions do not. In Indian history, by a strict definition, the Vedic and Puranic 'periods', the advent of Buddhism and Jainism, until the invasion of Alexander III the Great, is proto-historic.
Pre-historic Is the period from which life appears, in this case, referring to human life, until the commencement of writing. The Indus Valley Civilisation is, for us, pre-historic; there is no written record.
The ages of the artifacts found in the remains of the Ancient Civilizations throughout ancient India has been confirmed by carbon dating....and the contents of the Vedas have striking similarities with the artifacts found.....this is how the approximate date of the Vedas has been confirmed......
Bollocks.
Please do some elementary exploration of how the age of the Vedas is estimated.
It is one of the platitudes of Indian history that the linguistic record and the archaeological records do not touch, and you have it exactly opposite.
This is how History is confirmed world wide......If you have any other method, let us know....
History finding archaeological connections is pure bonus, and historical research is not conducted based on archaeology, but on the comparative analysis of historical, meaning written sources, including epigraphical sources.
