What came first protein or RNA?

So what makes more sense? The genetic material forming first or Protein forming first? As far as I understand, there are three things necessary for the most basic of self synthesis. There would have to be an RNA, a protein to that is coded for by the RNA that replicates it, and a unit the builds that protein based on the RNA molecule. I'm interested to hear what people think, and the logic that brought that to their conclusion, my guess is that RNA would have had to existed first because in certain situations, an RNA molecule can fold to act as an enzyme.
