Natural selection is selection. Selection involves intelligence.
Nobody knows how evolution works. There is no known evolution process that takes us all the way from inanimate material to life to human life. All current evolution processes have gigantic missing/unknown areas that do not make the process complete enough to work.
If we figured out a working evolution process, we still wouldn't know if that process was the process that made life. Why not? Because we were not there to watch it happen. It might have happened some other way, even if that way were a different form of evolution.
In addition, the greatest scientific law is cause and effect. Cause and effect means that everything that exists was caused by one or more things causing it to exist the way that it exists. Science is continually attempting to find out the cause for everything that exists.
At the same time science looks for causes, neither science nor any other process has found anything that acts according to pure random. Everything was caused that we can see. This means that everything has been programmed. Programming needs a programmer. And programming of something as great as the universe suggests a very intelligent Programmer. Such a Programmer fits our definitions of the word "God."
