Do the Titans of Greek mythology play any part in pre-Olympian mythology/worship practices?

by a-horse-has-no-name

I was discussing with someone how many religions base themselves off the practices and mythology of older religions, and it came to me that the pre-Olympian primal gods (Gaea, Uranus, Oceanus, Hyperion, Typhon, etc) that were later supplanted by the Olympians could have represented that same process in action, especially as many of the Titans represented natural aspects that would later be represented by a Olympian. Is there any evidence of that?

Here is another answer by u/KiwiHellenist. While the former talks more about theology and linguistics , this one is more technical about the different competing theories involved.
