Cell membrane and Proteins

I am not a biologist or anything, but today in school I was taught that through a mixture of gasses and a spark amino acids are formed, and then they linked together to form protein. But in my Moms college book it states that the cell needs to be LIVING in order to link together properly. So how did the amino acids form to make proteins which help make cells if the cell ALREADY needs to be LIVING to link them?Also: Cell membranes are a 2 layer membrane of lipids, BUT lipids only form from LIVING cells.
