"There have been species of microbes discovered in NASA clean rooms that not only evade disinfection methods but also adapt to using cleaning agents as a food source."
"also shows that even our best efforts to create a clean room environment are not enough to prevent life from finding a way in, something that has likely already introduced extraterrestrial Earth microbes to the moon and Mars."
There have been species of microbes discovered near your butt that not only evade disinfection methods but also adapt to using poo as a food source. Even our best efforts to create a clean bathroom environment are not enough to prevent life from finding a way in, something that has likely already introduced extraterrestrial microbes to Uranus.
that's how evolution works. Some are resistant but they struggle when the rest of the population is there to eat all the resources. But then we kill all that "rest" and the few resistant ones suddenly have all the food for them selves.
