My addition:
The RNA world hypothesis uses evidence that Boron stabilizes free floating RNA and notes evidence that early Earth had quite a bit of Boron in the water. So RNA can develop first as postulated and remain stable for quite some time.
Also, RNA could polymerize in early Earth's high ultraviolet battered surfaces and oceans.
