It would be less messy in the DNA, there is a lot of randomness, a lot of residual artifacts of evolution in our (and everythings DNA) due to the most likely cause being evolution. SO if we were (say) engineered, by an advanced species or Deities. IT should be less dodgy.

I am not sure how we would know if humans have been genetically altered the same we use forced evolution.
I dont mean from a monkey I mean they seed a planet or terrarium form to create life and come back periodically altering the environment or species with little tweaks. What if they only come back every 200k years and did little things like we do with animals and plants. Synthetic selection, selective breeding, genetic engineering etc..
After all how did we end up needing iodine?
I joke there but, I think if it's possible we are an experiment it ia more like a terrarium and little forced evolutionary things are done not new species entirely.
There may come a time we merge with computers and reproduction isnt needed. When we start editing for diversity.
Again there is no evidene in our DNA that it was messed with.

Isnt there something in the ancient alien crowd about fused chromosomes or something? Or some evidence of genetic manipulation?
Obvious I dont know if this is true or not, just remember hearing it.

$eriously though, can we really know what the universe consists of just by looking at stars we can barely see & sending an automic robot to grab chemicals that are to light we can not contain them in our vessels. So they basically are not even grabbed because we do not have an air tight enough box to grab universal juice haha. Sure we have some anti matter properties though can not seem to capture them properly to tweak. We have no clue what the universe is made of, these are good theories that help the understanding though we should all no that common sense tells us we hace no clue what this universe it. Hell it was just 200 years ago we figured out microscopes to see smaller chemicals so we think we are gods that know all because we see the big little stuff.
Anyone who thinks subotomic particles are small are clearly mistaken, in another 200 years they will be as big as our elemental charts chemicals to us now. They obviously will still be the same size, this world got real small & little chemicals got real big. We are always seeing smaller to get bigger. It does not stop here & this universe is huge & not made out of the same chemicals through its whole structure, no advanced organism is.
Some deists believe in Jesus Christ, while others do not.
The team found adenine and guanine, which are components of DNA called nucleobases, as well as hypoxanthine and xanthine. DNA resembles a spiral ladder; adenine and guanine connect with two other nucleobases to form the rungs of the ladder. They are part of the code that tells the cellular machinery which proteins to make. Hypoxanthine and xanthine are not found in DNA, but are used in other biological processes.
Also, in two of the meteorites, the team discovered for the first time trace amounts of three molecules related to nucleobases: purine, 2,6-diaminopurine, and 6,8-diaminopurine; the latter two almost never used in biology. These compounds have the same core molecule as nucleobases but with a structure added or removed. It's these nucleobase-related molecules, called nucleobase analogs, which provide the first piece of evidence that the compounds in the meteorites came from space and not terrestrial contamination. "You would not expect to see these nucleobase analogs if contamination from terrestrial life was the source, because they're not used in biology, aside from one report of 2,6-diaminopurine occurring in a virus (cyanophage S-2L)," said Callahan. "However, if asteroids are behaving like chemical 'factories' cranking out prebiotic material, you would expect them to produce many variants of nucleobases, not just the biological ones, due to the wide variety of ingredients and conditions in each asteroid." The second piece of evidence involved research to further rule out the possibility of terrestrial contamination as a source of these molecules.
The team also analyzed an eight-kilogram (17.64-pound) sample of ice from Antarctica, where most of the meteorites in the study were found, with the same methods used on the meteorites. The amounts of the two nucleobases, plus hypoxanthine and xanthine, found in the ice were much lower -- parts per trillion -- than in the meteorites, where they were generally present at several parts per billion. More significantly, none of the nucleobase analogs were detected in the ice sample. One of the meteorites with nucleobase analog molecules fell in Australia, and the team also analyzed a soil sample collected near the fall site. As with the ice sample, the soil sample had none of the nucleobase analog molecules present in the meteorite.
Thirdly, the team found these nucleobases -- both the biological and non-biological ones -- were produced in a completely non-biological reaction. "In the lab, an identical suite of nucleobases and nucleobase analogs were generated in non-biological chemical reactions containing hydrogen cyanide, ammonia, and water. This provides a plausible mechanism for their synthesis in the asteroid parent bodies, and supports the notion that they are extraterrestrial," says Callahan. "In fact, there seems to be a 'goldilocks' class of meteorite, the so-called CM2 meteorites, where conditions are just right to make more of these molecules," adds Callahan.
