(not OP) Another clarification: before you said "non-earth life". Panspermia[1] implies Ceres and Earth life are related, so that native Ceres life is hard to distinguish from Earth's (and arguably is the same as Earth life).

To be more precise: what I meant is life on Ceres that hasn't come accidentally from any of our own probes since eg the start of the 20th century.

I'd be happy to pay up in case of pre-historic panspermia.
