[Star Wars] Who was the first Jedi, How were the Jedi founded?
gpt
In canon it's unknown as of yet. But the Jedi order is believed to predate the founding of the Republic and to also have come from coruscant as evidenced by the shrine in the dark underneath the Jedi temple. It's all speculation as the shrine predates the Republic and isn't of Jedi origins.

Legends the Jedi are a successor order of the Jedaii. A loose group of force sensitives brought by Kwa vessels to Tython in the deep core somewhere around 30,000 bby. The Jedaii history is mostly lost to time but they played an influential role in the downfall of the Rakatan empire. Sometime between 27,000 bby and 6,000 BBY the Jedi order was founded from the Jedaii descendants.
