In time or length?
In time - a major cave can take 10 or 100s of thousands of years to develop, and if it still carries water it is still developing.
In length - anything from a few feet to the something like 390 miles so far known and measured inthe Flint Ridge / Mammoth system.
Erosional caves are formed by the action of water or wind.
No. Most caves are formed out of limestone making that false.
The Maquoketa caves in Iowa were formed through years of natural non-glacial erosion.
Wookies live in trees, not caves.

Limestone caves are formed through a process called chemical weathering. Rainwater, which is slightly acidic, dissolves the limestone rock over time, creating small cracks. These cracks then widen as more water flows through, eventually forming caves. Additionally, some limestone caves are formed through the erosion of underground rivers.

They - or it? - are normal karst caves, formed in limestone by its dissolution by water. I believe they still carry a stream: if so they are still forming.
Other way round! Water and/or air are in caves.:-) Most of the world's caves have formed / are forming in limestone.
Karst caves, and it is the majority of caves; formed by acidic ground-water dissolving the limestone.
Caves have been around for millions of years, with some of the oldest known caves dating back to at least 40 million years ago. Many caves are formed through a process called karstification, which involves the dissolution of soluble rocks like limestone over long periods of time.
