So what you need is water,phosphorus,carbon,oxygen and nitrogen.If you have that in the right proportions, life can in principle be created through chemical reactions. But if all of that is present, then by means of synthesis molecules can break down and form in the form of nucleotides. And it is shown that nucleotides can form then micro organisms can form from them and it has been shown how we came into being. The origin of life does not seem like such a mystery to me
