The whole scientific establishment is in shambles. They don't know what DNA is...
DNA: Deoxyribonucleic Acid. It's a polypeptide chain - a type of polymer - composed of a dual backbone of glycophosphates attached to combinations of matched base pairs.
they don't know where it came from....
Polypeptides as complex as DNA (and even short DNA chains) have been observed to form in certain conditions without the need for human interaction. Just mix up the ingredients and let them sit. Lots of polymers form that way - like superglue, for instance.
they don't know what it does...
It encodes time- and stimulus-sequenced information for the production of proteins from amino acids and other components, which are necessary for cell and organelle building, repair, and regulation.
they don't know how the information got there.....
Well, for starters, there's evolution. If there's a mutation in DNA (and there are several types of mutation possible), sometimes it will produce a new trait in an individual - via how cells are built, repaired and regulated - when enough mutations occur, and that trait may be passed to offspring. If the new trait is adaptive, it may be selected for preservation in the species. If the new trait is maladaptive, then the new trait will be less likely to be passed to offspring. There are other ways this can happen as well.
they don't know what role it plays (if any) in the construction of organisms
DNA is the blueprint of every cell or fibrous material produced in your body. So it has everything to to with the construction of organisms. Organisms are an emergent property of genetic code - of which DNA is only one type.
Gee, Supersport - wait, it's Guzman now, right? Gee, Guzman...I'm not even a scientist, and I didn't have to look up that Wikipedia article to write this. I've just had a couple of introductory biology courses in college - which were taught by scientists, I might add, who have proof to go along with the information. Oh - and the only observations we can make of the universe are effects - sight is an effect of light striking rods and cones in your eye, taste is an effect of chemical reactions on your tongue. And they're all about which molecules go where, too.
Your argument doesn't work, yet you keep spouting the same things over and over again like a broken record.
So, the only person bordering on mentally insane is you.
