The question is scientific because it is testable and verifiable.
Reason: claims about life on a Saturnian moon can be framed as testable hypotheses (e.g., specific gases produced by biology versus abiotic processes), and they can be investigated by observations, measurements, experiments, and models. Being about “aliens” does not make a question unscientific, and it’s not scientific merely because it concerns astronomy — the key criterion is testability/falsifiability.
