Really the point here is that there is a certain amount of randomness and an absolute fuck ton of pathogens anywhere you might try and clean.

If you fire a billion cars into the sun at slightly random trajectories then one might just skim the outside of the sun as it melts and have enough energy to fly back out without getting utterly incinerated. Thus we could not say that the sun destroys all cars, but also if you fire your car into the sun you’d be a fool to expect to drive to work the next day.
