Evolution is not quite that simple and the 2nd law of thermodynamics applies to isolated "closed" systems (systems without an external energy source) not "open" systems like the earth where we essentially receive ceaseless "on-demand" energy from the sun. This can occur on earth for a very long time even though the universe is an inexorable slide towards increasing entropy.

There are many examples of order arising from disorder in nature. Oddly, order can spontaneously arise only in systems that are not in "equilibrium". For example is there any meaning to say there's entropy in a frog?

That aside he should still be able to remember the scientific method and things like "never vaccinate into a pandemic". We learned the scientific method in 4th grade.

I showed him directly from literature from our studies that you don't vaxx into a pandemic. He's reply was that MRNA technology has changed science and that that no longer applies.
