Great slippery slope you have going there!
When I was a child, I read the bible, got taught things from it and went to Sunday school. I also read encyclopaedias and learnt about dinosaurs (I used to know all the names). And basically by the age of seven I had put two and two together and worked it all out. I remember a Eureka moment in the bath when I realised as much as I wanted to believe in Santa Claus, the Easter bunny and God it didn't make it real.
And then I realised there was no authority in my life I could do what I wanted! I turned to drugs and alcohol to fill the giant gap in my life and killed my brother in a fit of rage. Oh wait... I didn't. Because no one
needs God for morality or direction. It comes for within. I take responsibility for my own actions.
Inthebox the clotting cascade is a fantastic example of how evolution can not only explain a complex process but also be used to test it. You test evolution by making predictions based on it and seeing if they are correct this article summarises this.

It also demonstrates how something that appears irreducibly complex can exist in function parts that are later assemble or built upon. I hope you take the time to read it.
Of course the clotting cascade in itself does not prove evolution (also I did mention before proof is a mathematical concept so defunct for this argument anyway) but the numerous other process that contribute with it are what makes it a scientific fact.
