    I like the “aliens come from our imagination” and then links to conditions for life.

    water, atmosphere with oxygen, food (mentioned with respect to soil, but note that plants use light and gases for food).

    Interestingly, we think that life evolved on Earth without oxygen and the presence of oxygen itself (or might not!), since oxygen reacts with so many things, that if it is present in the atmosphere of another planet, it must be being produced – and one of the ways to produce oxygen is from plants/life.
