The word translated as 'human' namely, 'manussa' means 'high minded'. It does not mean a 'homo sapien'. SN 56.47 describes the meaning of what is not the human state, as follows:
Sooner, I say, would that blind turtle, coming to the surface once every hundred years, insert its neck into that yoke with a single hole
than the fool who has gone once to the nether world would regain the
human state. For what reason? Because here, bhikkhus...
...there is no conduct guided by the Dhamma, no righteous conduct, no wholesome activity, no meritorious activity. Here there prevails
mutual devouring, the devouring of the weak. For what reason? Because,
bhikkhus, they have not seen the Four Noble Truths. What four? The
noble truth of suffering … the noble truth of the way leading to the
cessation of suffering.
Therefore, it can be discerned quite plainly, without any dispute or contraversy, the human state refers to living a harmless righteous enlightened life, which is indeed extremely rare in this world of people devouring, exploiting, abusing, raping & harming themselves & each other.
