The genesis of Hinduism is nearly as elusive as its contemporary definition. Unlike Islam, which began with Mohammed, or Judaism, which began with Moses, Hinduism has no founder, nor any traditional time or place of origin; it emerges from the jungle as a continually evolving religious system. Scholars debate the primary source of what would become the Hindu religion.
christianity is 2000 years old, islam 1500 years old but hinduism was practised in indus vally civilisation which is 4000 to 3000 years old
That means it started way before 4000 years.
every religion has that one person that laid the outline or basic rules of that religion but hinduism is so old that nothing can be seen that far back in time .
Who was that man that laid the foundation of this religion five six or ten thousand years ago will remain a mystery forever.
