The issue focused on whether there is any possibility that living organisms could survive under conditions other than those found on Earth. 
 
 Most recent experiments show that both bacteria and viruses can survive at significantly higher temperatures than those found on Earth. 
 
 Our cells can survive even lower temperatures. 
 
 Yet these temperatures are outside of what could be expected on Earth. 
 
 Here are some examples of heat resistant life: 
 
 -Temperature resistant bacteria living on Mars 
 
 -Thermophilic bacteria living on Mars
