I’ll defer to JammyCakes on that one.
I’d be interested in hearing your thoughts on why we don’t get mega arthropods today if the earth is only 6k years old. Like, for example, Meganeura Monyi a proto-Odonata (dragonfly) with a 75cm (~2.5 foot) wingspan. If seagulls can survive a global flood, why not seagull sized dragonflies?
