What does the phrase no solvent no chemistry no life mean?

What I am trying to say here is that all lives are made up from chemicals and chemical reactions as life start to occur when there are chemical reactions but not saying which one comes first. If we have atoms which are physics-related stuff but no interactions among them (chemical reactions) then life will not occur.
