Is there really life on planet K2-18b? We can't rule it out, but some key questions must be answered | Nathalie Cabrol

Contributing sentiments towards policy:

58% : On the other hand, scientists can't fully rule out non-living sources, since they have in the past detected DMS on a lifeless comet.
57% : While the paper repeatedly stresses the preliminary nature of the findings and the need for further data, public statements by the lead author have at times conveyed a stronger sense of confidence than the published evidence supports.
46% : For instance, arguments that abundance of DMS or DMDS inferred in the atmosphere by the study is difficult to sustain by non-living processes calls for developing new research that can theoretically, empirically and experimentally seek the existence of these potential nonbiological pathways.
