That 600MB is the result of millions of years of optimization. For every human genome that exists today there are many other genomes which were tried and discarded over the years. It also contains a remarkable amount of compression. Even if you assume that a genome contains a complete template for a human (it likely doesn't) the fact that the compressed version is 600MB doesn't really relate to the unpacked amount of information. Especially since the compression has seen millions of years of optimization.
