Other way around actually. Judism/Christianity claim to be 4,000+ years old but there is little evidence to back this claim that wasn’t written centuries after the supposed fact.

Hindu religion has temples and manuscripts dating at least that far back and its known that sporadic trade from Rome to China did happen and lands that are now in modern India were a leg on that unofficial trade road. So the various authors of the old testament very well could have had copies of Hindu writing and tales, or been told them second, third or fourth hand through those with a connection to the unofficial trader networks that moved goods and information between the two continents.

Now that’s a load of BS if I ever seen one, not as bad in Bible but still par. Hinduism books based on islamic or Christin ones? Like from 19 th century that’s possible, but anything before that highly unlikely.
