I note that you lump “evolution” into the “natural processes” that you see around you. That is simply begging the question: IS natural selection a real, natural process like growth of a embryo into an adult, etc.? In order to make the connection between the two, you need to make the leap from the observable (embryo into adult) to the unobservable (evolution of species). My point is that this is no more “rational” than making the leap from the observable (my creation of the note to my friend, or a complex machine) to the unobservable (a creator’s creation of complex organisms).
If you’re presented with the fossil record, the only rational explanation of transition fossils is a transition between them. Otherwise, you’re into the ‘God set things up to trick us’ realm.
