I love listening to Lex and his guests . I do have one I think very practical question here . Why do we just assume that “another life form” needs water to survive? Understanding we do and so many life forms do but what about a race that r so advanced or have never had an interaction with water/water source? I do believe sometimes as human beings we have the answers to so much only to find that we know very little in the big scheme of things. Science leads us to believe water “needs” to be present to survive but WHAT IF it doesn’t for e another form of life ? Thank you /enjoy your podcasts Lex
