The only problem is they AREN'T Buddha. Any of those 24 :-|

DOn't need to be. In any case, the only dates that place Jain origins prior to the Buddha are "traditional". Even those dates "overlap" the foundations, with the first Tirthankars being no earlier than 850 BC, and the last well within Budha's lifetime.

I think it's safe to dismiss the "traditional dates" as probably having a political origin.

Jainism used to be a much bigger element in Indian religious life than now ~ just like Buddhism.

Here's a thought for you ~ being a Jain carries with it all the burdens of the highest levels of Christian morality with none of the benefits.
