The rocks to humans example comes from public school text books. Life originated after it rained on the rocksfor millions of years, is what we're taught.
In other words it's a misrepresentation - nobody taught "rocks to humans". And the origin of life is hardly "basic stuff" for evolution at all - not only for reasons of the scope as I explain below but because it is the focus of advanced research and we do not currently have a good explanation for all of it.
Just to show how important the origin of life REALLY is to evolution I have a University level textbook on evolution. The origin of life occupies one page out of more than 660 (NOT counting the glossary, references or index). And it doesn't even mention rocks playing any signficant role.
SO where do we draw the line - it's not a case of arbitrarily stopping anywhere. Evolution is what happens to life - one of the features of life - replication is needed for the basic mechanisms of evolution. So that is where you stop - the origin of replicators is outside the scope of evolution since the theory does not apply. The scope of evolution is how replicators can change and diversify over time. Your approach amounts to "lets lump together everything that ever happened and call it evolution" which is really not very useful.
