First, Australopithecus is considered an ancestor of Homo under
current conventions. I personally like the good Doctor's model
where it's not but, under current conventions it is thought of
as an ancestor.
Second, an ancestor of Homo isn't Homo.
This brings us full circle:  Evidence for tool use extends back
further than Homo and you didn't know this.

Second, since you need really special conditions to preserve bones, and you don't need any conditions to preserve stone tools, it is the simplest possible logic (which you are unable to do) that the stone tool of Homo will preserve better than the bones of Homo.

Ironically, the best evidence for pre Homo tool use is cut marks
on bones.
Wow. You're doing  /Terrible/  here.
