Here's a question for you:  what is the oldest name still used by people today?

I had this fun conversation with Aven and Amalia on twitter yesterday, and we weren't able to come to a decisive answer.  Aven cleverly suggested Eve.  Amalia thought maybe Krishna.  My idea was Inana, who appears in the Epic of Gilgamesh.

Some rules:

It has to be a name either written down or provably used by a real person of ancient times.

To be counted as still in use it has to be a name chosen by parents or in some sense natural (i.e. not one deliberately adopted in later life).

The floor is open for suggestions!
