Life on Earth started before the high-oxygen atmosphere we have today. The oxygen content in our atmosphere is a result (byproduct) of life.
It's true that a lot of the current exploration is focused on places with liquid water.
107 is lethal for humans (and presumably closely related animals). Other species we know of find that downright chilly (thermophiles).
Presumably, if the other conditions are right, then photosynthetic species may be able to adapt to a variety of solar outputs.
Life on Earth has managed to survive in a wide variety of conditions...high/low pressure, high/low temperature, aerobic/anaerobic, acidic/alkaline, high in the atmosphere/deep in the earth, lots/little water, lots/no sunlight, etc.
I think there are many chances for suitable environments, particularly for microbial-type life. The trick would be in whether life could get started. That process is not well understood.
