Words have meaning. I won't be persuaded to use different words, even if the choices are synonymous. Your inquiry is digressive.
The use was not "found." The use existed all along. The use was, is, and will continue in use. It does so whether humans are around to "find" use.
Except it's not a "weaker argument" on my end. The teleology is not in dispute, or if you dispute it then I'll simply acknowledge we disagree and move on. Humans didn't find the use of DNA. We have added to
our ability to use DNA, but that is only because that functionality already exists. We didn't "find" the use, we use what has already been in use by the individual organisms apparently since the beginning of life's existence. So, NV, while I appreciate the critical thinking I'd encourage you 1) not to take an adversarial approach and search for holes but instead build from consensus, and 2) you discard this misguided idea humans "found"
the use of DNA when in fact DNA is and has been used by organisms apart from human existence for millennia.
Excellent example. An "A," preceded by a "P," and followed by an "R," then followed by an "L," followed by an "E" are identical whether written in crayon or Sharpie, whispered or shouted, built of wood, etc. Those litters, in that order mean the same thing no matter what they are written in. Those letters in that order mean something in English. That is perhaps a meaningless order of letters in Somalian or Japanese. If we were someone who didn't understand English the word those ordered letters form would be meaningless but that word has meaning. Once we understand how to read or hear English we understand the meaning of the ordered letter but it was not our understanding of English that gave the ordered letters meaning. It was our learning English that enabled us to understand the meaning of the word - the meaning that had always existed in that word, whether written in crayon of built of wood.
Something or someone "spoke" a "language." That language is evidentially the oldest language ever discovered by humans. It's written in very, very small letters, not with crayon or Sharpie, but with nucleotides. We didn't know what it was and when discovered we didn't know how to "read" it, or understand it because we didn't know the language. The meaning was not assigned. The meaning already existed.
(josh grins) That DNA "
tries"? lol. You're not assigning motive, intent, or volition to chemicals are you? This is part of the problem, NV. Watch for it. Even the most ardent of antitheists use language poorly when they speak of these kind of issues. Chemicals don't actually "try" anything. At least not in a strictly materialistic paradigm they don't. If there is some sort of already-existing programming involved then there is a reason affinities for arsenic and phosporous exist. Your particular example speaks of one of the other concerns I broached in my op-reply but I'll stick with the existence of inherent information.
Arsenic is an example of ordered chemical structure. It's not very complex, either. You cannot rearrange the chemicals in arsenic and it still be arsenic. It is not an example of ordered chemicals with meaning. Humans use arsenic attributively. Humans do not assign the meaning of DNA to DNA; we use that meaning functionally, meaning that has already existed long before we understood it.
Those aforementioned letters can be re-arranged to "say" PEAR, instead of PARE, or they can be arranged to say RAPE or PEER or REAP and all still have meaning within the context in which they occur, not a context humans assigned after the fact. RPPR is meaningless in English, so it is a limited analogy (I'm not aware any sequence of CGAT is wholly meaningless).
Then I encourage you to investigate the matter and to do so as objectively as you can. The existence of inherent information is one of the most resonate arguments for the existence of pre-existing intelligence. Maybe one day that will change, but for now it's a reason for you to reconsider the existence of God and perhaps treat your nihilism nihilistically
