It kinds of hinting on the hypothesis, that life will emerge the moment it will get a chance to emerge - there is indirect evidence of unexplained fossilized structures from Mars, Phosphine gas on Venus, now organic molecules on Enceladus, I would consider it very likely that there is going to be life on Europa, at least microbiological.

structures from Mars: I'm not sure that a geological origin was discarded. Wait 5 years until the dust settle.

Phosphine gas on Venus: I think it was debunked.

now organic molecules on Enceladus: And there is plenty of organic molecules in Titan, but they are created by inorganic reactions. Something like https://en.wikipedia.org/wiki/Miller%E2%80%93Urey_experiment at a moon scale. (Note that the modern versions use a very different gas mix, but the end result is similar.)
