True. But the DNA is much more complicated and information rich than any computer program. Where is the credible naturalistic explanation for DNA’s informational origin? What other mechanism other than intervention by an intelligent agent can explain it to date?
Historically, how many subjects of scientific inquiry cannot be said at some point to not have a credibly naturalistic explanation, and were attributed to the action of some external intelligent agent?
Evolution. Some details are taught in schools, some more at the college level. By the way, there are non-deterministic algorithms, which out of chaos either create complex and information-rich data (e.g. programs for de novo design of peptides/proteins, based on Monte Carlo or genetic algorithms) or even self-program certain capabilities (e.g. artificial neural networks).
