I mean, lots of animals use tools, including chimps. those tools aren't nearly as sophisticated, so it depends on how you define tool use, but the point still stands. this is all besides the point.
It depends on how you define 'human'. Our line spit from chimpanzees 7 million years ago (mya); we walked upright 6 mya. Tool use began ~2.58 mya (possibly 3.3 mya, depending on some uncertain evidence).
