Can bacteria still exist in high temperature sterilization environment?

That depends on how long it takes to kill the virus. Some bacterial eggs can be "boiled" in boiling water for half an hour without dying. As for the existence of bacteria in the crater, you said that life exists widely. Human beings' definition of life is not accurate, nor is the definition of the conditions for life. Humans define the conditions of life with their own conditions, or define the conditions of life with the most common environment on earth. More and more so-called harsh conditions for finding life have gradually subverted the narrow definition of human beings. Those so-called and special environments, such as high temperature, low temperature, lack of oxygen, high pressure and so on. It is special only for human beings, but it is necessary for those who are not known by human beings to survive. Just like anaerobic bacteria, it is unimaginable for human beings that they cannot survive when exposed to oxygen. These new discoveries can change the existing textbooks and expand the thinking of human beings to discover new life. Maybe it's not surprising that we find alien life on nearby planets in the near future!
