In addition to what other people have indicated, there's a long tale of competing theories. There's very limited evidence of human settlement in the old crow flats as far back as 40kya (which is still 20kya after the settlement of australia), but unfortunately this evidence (butchered animal bones) are circumstantial and the dating is not reliable.

However, i think ~23kya is a pretty safe bet at this point. And there are dozens of sites before 14kya as far south as chile. Clovis first has been largely rejected for about 30 years now but the old narratives keep floating around.
