If you wish to dwelve into how a seed can turn into a flower or a tree, or how a simple sperm cell can fertilize an eggcell, only later to become a human being, I suggest you start looking into the matter by reading some biology. Even though it seems very magical (which it truly is), there are definitive biological and chemical processes going on to allow for this to happen - processes that are studied thouroughly and understood fairly well within science.
As for the whole meaning of life thing, this is always under much debate. However, all evidence suggests there are no ultimate meaning or purpose to life, or the universe at large for that matter. From the perspective of biology, the purpose of organic life is simply to sustain its living only to replicate and bring on its genes to later generations. There is no grand scheme going on. Of course for us humans, with developed intellects and cognitive capacities, life becomes more than just surviving in order to replicate, so we all find our own purpose in life. But there seems to be no objective, absolute and definitive grand scheme to things, just individual truths about what the purpose of ones life ought to be.
The analogy of yours that the solar system is like an atom is flawed for several reasons. It was originally thought that the electrons orbiting the atomic nucleus were much like planets orbiting the sun, but we know this is not true. The solar system analogy is simply useful for us in order to try to visualize how atoms works, since the truth of the matter is far more complex and weird than our petty minds can comprehend in an intuitive way. Electrons simply don't orbit the atoms like the planets orbit the sun, not even close. In fact, they don't really orbit in the usual sense of this word, and the nature of the interactions governing planets orbiting the sun and electrons surrounding the atom are fundamentally different.
