Sacred texts, as per historians

Unlike Ibrahimic beliefs, Sanatan Dharma, known as Hinduism, has no one book, such as the Torah, the Bible or the Quran. People may claim or say that the Bhagavad Gita, the song of God, is the Hindu Bible, which is far from the truth. The Gita is the closest comprehensible and consistent text, yet it's only a minuscule portion of Dharmic Hindu literature. Western scholar dates its composition to the 3rd to 2nd century BCE, while Buddhist monks claim that it could go as far back as the early 1st millennium BCE.

The oldest preserved manuscript is estimated to have been composed from the 1st to 2nd century CE, currently in the Bodleian Library, Oxford, in the UK. Other, partial scriptures are carved in some Edicts of Ashoka and remote temples across South-East Asia. Obviously, conquest and climatic catastrophes have destroyed many manuscripts and carvings of Sanatan Dharmic texts, yet the famous Gita has some form of reliability.

Nonetheless, many Indologists and Buddhist monks theorize it is older than credited since the entire 700 verses is a conversation between Krishna and Arjuna, a character from the epic, dating during the early Vedic period (1500 to 500 BCE). Also, archeologists have recently discovered a submerged city within the Gulf of Cambay off the coast of India's modern-day state of Gujarat associated with this epic. The government suddenly stopped the excavation after Carbon 14 dating placed many artifacts to be as old as approximately 9500 years old. This alters Western scholars' Cradle of Civilization theory, which meant Dwarka (submerged city) preceded the estimated Indus Valley, Mesopotamia and Ancient Egyptian culture’s timeline. Therefore, these are a few reasons why Sanatan Dharma’s origin is vague, inconsistent, complex, and speculative.
