Chemicals that we shouldn’t find unless they are produced by life forms are sparking interest in exploring Venus from both public and private sources:
And, who knows, it is even possible that the life on Venus would turn out to be organisms that somehow survived an escape from Earth during the early days of all the planets’ formation. As renowned chemist James Tour points out, origin of life is an extremely difficult problem. Once life actually exists, extremophiles are showing that it’s unwise to make rules about how it could continue to exist.
Note: Here is what life on Venus would be like for a human.

Is this idea too crazy?: There was life on the early Moon? Not quite as crazy as some might think. The early solar system was very different from the current one. We won’t know for sure unless NASA’s Artemis project finds microfossils on the Moon. But it’s possible that, as with Mars, early life got started but died out.
