LOL. You asked how is that the earth's shadow. Well, it's NOT. You preach doing your research but you don't do your own. And then you said to not be mad if you can't handle the answers. Then you got mad when I gave you the answer.
You can do this with a stick and a ball and see how it works. It's super simple. I don't know why you think this is so complex.
