Okay so I’m sure if you’ve read in history that sometime around Jurassic age that insects were like stupidly big due to O2 saturated environments. why can’t we manufacture an enclosed space with gradually increasing oxygen saturation over a few generations and see how big we can get insects?

Evolution works very slowly. It doesn’t just make things bigger – over thousands of years, if being bigger for a species is an advantage, the larger ones will gradually breed more and survive more than the smaller ones and then the species gets larger. The tradeoff is larger animals need more food and burn more energy.
