Your scare quotes notwithstanding, I see nothing defiant of reason or arbitrary about biological classifications.
Yes, recent DNA analyses have shown more complexity in such classifications than previously suspected, but they are still very reasonable categories for understanding the natural realm.
.
The complexity you claim to admire is from the moment of creation.
You simply are rejecting the realities real science has found.
Space,time and motion are inseparable.
If you want time beyond the available 6000 years at our location, you need to find a way to get there,and you’d better hurry, because space-time is scheduled to be un-created in about 1000 years, at the end of the 1000 year demonstration of the total depravity of man.
