Bioligist create DNA capable of evolution

Synthetic DNA and RNA has been shown to be capable of evolving in the lab, carrying hereditary traits with it.The synthetic form of dna lifes building block was able to share information with real DNA and do directed evolution into biologically useful forms.Scientists are studying the main question about DNA where did it come from.One idea is that DNA, which is built with deoxyribose sugars evolved from a simpler form of rna, which is built from ribose sugars. But then people ask where did RNA come from?
This is a big question, John Chaput said from  Arizona State University. If the RNA world existed, how did it come into existence. Was it magicly produced or was it the product of something that was even simpler than rna some people wonder.
