Which is the oldest languages among these two kannada or Telugu?

It's tricky to definitively say which is *older* between Kannada and Telugu, as they both have a long and complex history with uncertain origins.

Here's what we can say:

* Both languages have roots in the ancient Dravidian language family. This family is thought to be one of the oldest language families in the world.

* Kannada is believed to have emerged as a distinct language around the 5th century CE. It is considered one of the oldest surviving Dravidian languages.

* Telugu is believed to have emerged as a distinct language around the 7th or 8th century CE.

While Kannada is considered to be older, both languages have a rich history and literature spanning many centuries.
