As an (presumed) "adult", do you drink milk or consume other dairy products? Or are you lactose-intolerant?First of all let me say that creationism does not run counter to natural selection. However, evolution DOES run counter to biological science! Any time you have a naturally occurring change in a genetic structure, it's called a 'mutation' and to this day mutations are never a positive thing. They result in D formations, diseases, and things like that. And besides that, when I stand on a mountaintop at sunset, just as God created me and watching the world around me shift from day to night as the place where I'm standing passes through the terminator line on the planet's surface, I see nothing but evidence of creation. Sorry, but I don't see things that used to be pond scum that somehow decided to become trees and the other millions of life forms before me!
The ability for adults to digest dairy products (from other species, mind you) is just ONE of a host of 'beneficial' mutations that most humans have today.
Appreciating nature, and ascribing the wonders therein to God is fine, but you should learn more about the mechanisms (described by science) as to HOW He did it -- at least to our best current knowledge.
