ronrsr: Please see famous Ramban at the end of parshas Bo (and in his piyrush on Iyov, spoken about in detail in sifrei chofetz chaim as well, and many others) where he clearly puts forth his opinion with regard to teva, there is no teva. Hashem did not give over the world to nature, he continues to directly control each and every thing that goes on in the world each and every second. Chazal teach us that one does not stub his toe without a direct command from hashen, nor does a blade of grass grow.
As such, there is no such thing as coincidence!
