Higgs boson or god particle is prove of how the universe was created so that there's no need to be a god to create it in the first place. Also when looking at the circumstances of how and when the bible was created (or by reading the bible and historical papers about that time) it becomes obvious that god is just a creation of mankind to use it as a tool to create peace and order. Christianity is very different from other religions because Christians accepted that there doesn't have to be a god but it's easier to believe there is than to try to explain how everything was created and so on. It's like Santa Claus. It's easier to tell children Santa brought the presents than to explain why we celebrate the birth of Jesus.
As for the suspended boy. He did show this toy to a friend in the schoolbus on his way to the kindergarten. They handled the situation very poorly especially interrogating him about it without the parents can traumatize people. Punishing him was right but interrogating him so that he wets his pants is too much. I don't think that this boy understands what exactly he did wrong. From his perspective it was probably something normal to show one of his friends his newest and most awesome toy even if it's debatable if replica guns and replica weapons should be toys at all.
