Problem:
Verging on the realm of science fiction, my question is that is there any theoretically possible way, biologically/chemically, with which the entire human race can be killed without affecting the rest of the biosphere at all? I am only curious about theoretically possible no matter how unlikely.
Question: If we encounter a sufficiently advanced alien civilization bent on our destruction, would it be possible for them to make sure all humans die without harming any other living organism on our planet?
Question: Is there anything biological/chemical which makes us unique or different than other lifeforms on Earth? Something which can be used against us?
Question: Are we just so similar with a bunch of other species that we cannot be wiped out without other lifeforms getting harmed or our destruction cannot be ensured? Is it possible to artificially make humans extinct?
Does anyone know how to go about this search to explain it.
