Belief does not enter into it. Understanding evolution depends only on knowledge of the physical world. The existence of the process of evolution is an irrefutable fact. Life on this planet is old and has changed continuously since its inception.
You seem not to recognize these simple facts yet you espouse preposterous conjectures with no basis in reality in order to create the appearance of statistically impossible events that preclude the natural progression of life over time. Here is a simple test of your method. Try it going backward through time. Life begets life in a continuum. Life today is clearly different than life even in the recent past. Because you will be dealing with known events (probability one)at every stage you will be forced to recognize (if you are honest) the absurdity of your zero probability argument.
Microevolution is a fact. Anything else, including the so-called theory of evolution, in all its guises, is an ideological doctrine and a belief system, like communism or naziism. Try reading through my large post above for comprehension rather than simply for making your knees jerk. The arguments involving probability are sufficiently real. Evolutionism and mathematics are incomparible. You've got world-class mathematicians like Fred Hoyle and Bob Bass claiming macroevolution is impossible and you had the Wistar symposia at which a collection of the world's best mathematicians told the evos they were FUBAR. You're beating a dead horse.
