Even if we nuked the whole earth to oblivion, turn the surface into glass, and evaporated the seas, some microbes would still survive deep underground. What we really need is an asteroid impact that turns the whole crust into molten lava and splatters it all over the solar system. Even that method might not work perfectly, but it’s our best chance.
If we would kill bacteria entirely, we would doom ourselves inevitably.
But if bacteria killed us entirely, the world would go on with barely a whimper.
We must join the winning side, and become bacteria.
Hospitals are dangerous for children, the elderly and immuno-compromised patients not because of risk of contagion, but because the bacteria that have survived the aggressive chemicals hospital surfaces are cleaned with are the strongest ones (shamelessly plagiarised from my 8th-grade chemistry teacher).
