Question

Why human cannot find God in this structure ?

c:\myproject\src\
    main.as
    human.as
    com\god\
        God.as
        IGod.as

human.as :

import com.*;
public class human extend God implements IGod {

}

Answer 1

Because god is hiding in his own folder, and humans can only see files (ActionScript does not import recursively). If you import this way:

import com.god.*
public class human extend God implements IGod {
    ...
}

it should work.
