Archaeologist here, it’s heavily disputed if caves were that integral to our evolution. Issue is lack of studies. In much of Europe caves were very popular amongst researchers, but new studies began finding a ton of sites outside of caves. And remember this part of our evolution is not very significant. 99% of our evolutionary history we lived in Africa. Unfortunately the data is not as good and the areas not as well researched to say.
We do know many cultures have lived in areas for tens of thousands of years without access to caves.
What we can say though is people in regions with caves will use them at least seasonally
