What is the oldest religious text?

In Kakadu they have paintings reliably dated to 50,000 years or more.

My understanding is that it is from analysis of a few years ago,even more astonishing,and therefore controversial, is a claim I read in the press [and thus to be taken with a grain of salt or 2] that a site in the Kimberley has been suggested to be 80,000 years old or more.The report is a few years old and I haven't heard more.Of course rhat is a really old date ..aboriginal culture is truly amazing.Actually I would like to find out more about this myself but don't have the facilities.I might try to get more info..
