And the cell doesn't function if one of those chains of molecules isn't there, and you start looking at the complexity of life and the mystery of life, and then start thinking about things like the twenty universal constants, that if any one of them from Plank's minimum to the mass of a proton, if one of them is the tiniest bit off, there would be no life or possibility of it in the universe.
