Your post is physically inaccurate. Stars do not build complex atoms by decreasing entropy. They in fact do the opposite; by going from hydrogen to atoms with a higher atomic number, less energy is needed for the bonds. This energy is released in the form of light, which increases the entropy of the system.
Life manages to keep entropy more or less the same by using the energy released from the sun. It does not create order from chaos, it merely reshuffles the energy. But even life has its boundaries, hence people get cancer and other deceases.
