That destroys any possibility of finding out if there was or is life on other planets. Life that would be better evolved to handle the conditions.

It is also unlikely to do anything. The conditions are well beyond anything on Earth. Mars is near vacuum; life has survived in vacuum but didn't grow. Titan has liquid organics, but is really cold and microorganisms don't really handle hydrocarbons.

Those two statements contradict each other.

It's a given that Terran life would be poorly adapted to the conditions. So native live would overwhelm it.
