What Are the Chemical Building Blocks of Life?

We know the solar wind exists. We can measure the solar wind, and so we can model what would happen if we didn't have a magnetic field. There's modelling going on all over the place in all these studies. And i imagine also, there's a lot of it a sort of theoretical, kind of based on models of how the earth formed rit but for eximle, we can only go back so much with these methods.
