So I think this is someone’s wishful thinking. But for you exoplanet guys what if any chemical signature if found would definitely indicate life?

“This is K2-18b, a potentially habitable planet covered with oceans and about 2.6 times the size of Earth.
JWST has just detected carbon dioxide and methane in its atmosphere which can only be produced by living beings.”
