But, genetic mutations are possible. Ever heard of a peppered moth? They were designed to blend in with lichens but when the industrial age happened, lichens turned black from soot and smoke. Peppered moths camouflaged with these black lichens due to a random genetic mutation.
Or, perhaps better put as a description of how adaptations can result in an organism being better suited for its environment.As I said earlier, they got food other species couldn't so they were better off (the other species could only get the lower down leaves).
I think evolution is possible,and way more likely than us just appearing out of nowhere. But that does bring up a question; where did the first life come from?
