Already dealt with this creationist garbage some time ago.
Thanks to 80 years of prebiotic chemistry research, we don’t need an imaginary cartoon magic man from a ridiculous Bronze Age mythology to explain DNA. The same holds with respect to the biosphere, or any physical system of interest to scientists - relevant scientific research has provided proper explanations in terms of testable natural processes.
EDIT : almost forgot to mention a salient fact with respect to that above link to the document I compiled some time ago … when I wrote that, the list of references covered 96 scientific papers. That list has since been expanded, and I shall have to write an updated 2025 version at some point to reflect recent scientific advances, such as the advent of mechanochemistry and its application to prebiotic syntheses. A future version of that document could take the reference list past the 100 mark with ease.
