From the RNA world file:
New research looking at how the conditions on primordial Earth might have produced life has identified a mixture of salts that, mixed with heat flows from molten rock, could potentially have contributed to the formation of self-replicating biomolecules.
This self-replication is a key part of the ‘RNA world’ hypothesis: the idea that ribonucleic acids (RNA) can both store biological information and perform the required structure folding for life to grow and evolve into the state it is today.
In this case, scientists looked at the mixture of magnesium (Mg) and sodium (Na) as it might have been on Earth in its earliest years: for RNA folding to work, a relatively high concentration of doubly charged magnesium ions and a lower concentration of singly charged sodium is required.
“Accordingly, the question arises as to which environments on early Earth might have provided suitable salt conditions for such prebiotic processes. One geologically probable process that produces saline environments is the leaching of salts from basalt,” the international team of researchers writes in their study.

All these “hints” are simply trying to explain how life might have got started without any information at all.
But you know what they say: When you are in a hole, KEEP digging! Dig harder, harder…
This is part of the RNA origin of life claim:
