Such giant creatures do exist. Larger ones even.
By far the most robust theory for the mass extinction event that wiped dinosaurs out is the asteroid theory. Not there being a sudden extreme change in oxygen levels lol.
I think people get confused because afaik the reason today's bugs may be smaller due to the lower oxygen levels.
Doesn't really apply to T-Rex tho.
Which has to do with how bugs breath through their exoskeletons which is a function of surface area. Lots of O2 can support larger surfaces area bugs.
