Actually I've proven my point multiple times. In simply trying to argue physics and history with people who want to argue emotion and fantasy. Once the OP invoke "logic" (which ==rationality== science) this debate was over. Spartans fight in a fictional universe of the scientifically plausible fighting other beings doing things that are scientifically plausible. Even if it's a million years in our future. Guardians fight in a fictional universe of MAGIC. Where beings routinely do things that are scientifically IMPOSSIBLE against other beings doing the scientifically impossible. Channeling the power of a machine/entity that terra-formed two planets that are hot enough to melt Lead...once of which is exposed to enough radiation to scour the planet of ANY atmosphere it might think of having. The only thing that is keeping this conversation going is hero worship for The Master Chief. Full stop.
