I know what you are thinking. This is not a joke. It is a legitimate theory. You may be asking what I mean, the popular machinima series can't be canon, right? WRONG. In the very first episode of the series, the Red's banter about Master Chief and the events of Halo 1. Which shows MC and Halo's exist in RvB. Then there is also the Halo Ring on which it takes place. Which makes no sense as why they would be stuck on it. However, it reminds me of the Halo 5 Warzone map Raid on Apex 7. Warzone is simulation based training with red vs blue combat. My theory is that the Reds and Blues are testers of Warzone, before it was perfected. Which means the "Do you ever wonder why we're here" line feel weird.
