You probably mean “Jainism” (not “jaisism”), so I’ll answer about Jainism.

1. According to Jain belief

- Jain Dharma is anādi–anant – beginningless and endless. - The universe, the soul, karma and true dharma (right path) have always existed. - So from the Jain point of view, Jain Dharma is not “founded” at some date; it is eternal, revealed again and again by Tirthankaras (like Bhagwan Rishabhdev, Bhagwan Mahavir).

1. In terms of recorded history

- Modern historians usually talk only about what has written or archaeological proof. - From that angle, they generally say “we cannot prove which is the oldest religion” because very ancient periods have limited evidence. - So academically, they don’t accept any religion (including Jainism, Hinduism, etc.) as “the oldest” with 100% proof.

1. So what can we say simply?

- In Jain faith: Jain Dharma is an eternal, beginningless path of liberation, taught in cycles by 24 Tirthankaras in each time-cycle. - In modern history books: They may say Jainism is one of the most ancient living religions of India, but they avoid calling any single one “the oldest” due to lack of clear proof.

So, from a Jain spiritual view: Jain Dharma is sanātan (eternal), not just “old.”
