Phosphene detected in the upper atmosphere of Venus, possible evidence of microbial life?
(Venus is 400+ degrees C on the surface, but much cooler high in the clouds, any bugs would need to be tough though to resist the droplets of sulphuric acid!)
They found space cooties?????

Titan surface is probably far too cold to enable organic chemistry to proceed very far within the age of the solar system.
I also think organic life sign on venus is a mirage. it seem difficult to imagine an entirely airborne biosphere as no organics will survive even in the lower Venusian atmophere, much less the surface. how nutrients reach upper atmosphere, or will be steadily replenish is hard to imagine. i think we simply have not done adequate research to anticipate all the nonbiological chemical processes that can possibly introduce trace amounts of organic molecules into a nonbiological planetary environment.
That's how this ends up being substantial either way, I think. Let's go out on a limb (lol) and say we don't find life. We have found something without an immediately obvious explanation. Yet another way, other than biological processes, for those chemicals to end up where we find them.
