I'm guessing you don't know what a model is. It's a simple representation of a complex object or concept. A Bohr model isn't any less useful just because it's not 100% accurate. It's a perfect way to explain atoms without going into great detail. Show me a cell that can do that. Any cell. Any show that can not only harness and control such great amounts of energy, but can do so across distances and with great precision. While you're at it, get your ass to Africa and pick up a shovel. Start digging until you find a massive portal constructed by ancient aliens. Until you do so, you have no case for Halo being in our universe or needing to follow our universe's laws, so all of your arguments are meaningless.
