K2-18b life?
#3
The data on this planet looks very doubtful, and the detection of la biosignature is controversial. Additionally it is not dense enough to be anything except a mini-neptune, and planets like that won't have any dry land (the rocky core is probably thousands of kilometres below the visible surface). If there is any life there, it can only live in a very restricted layer of the water mantle, so wouldn't be anything like Earthlike.
