to be fair this makes creationism more plausible.
what idiot was responsible for the way humans turned out?
Like every living thing, via a long process of evolution/natural selection, and in today's world especially: personal choice.
Be very careful when discussing anything 'Eugenics' here, however. That topic alone is probably enough to get ME banned, just for mentioning it.
So why did I?
Simple- Genetics, and our (I call it utter arrogance/hubris) modern world's morbid fascination with playing 'God' with living things. Splicing DNA is just a faster and more diabolical way to achieve the same pursuits. Scientists have been using this in the livestock/agricultural fields for longer than I've been alive, and this momentum has only increased since it began. Between weaponizing already horrible diseases, to other experiments that are supposedly illegal yet everyone knows someone, somewhere, is doing it.
I harken back to the original Star Trek series, and that venerable antagonist, 'Khan'. He and his followers a product of genetic engineering of people, and of course the pros/cons of it (not to mention the referenced world war that was caused by it).
There is already enough history and all the wisdom we should never forget, about our prior indulgences in manipulating the human genome for political/theological/quasi-scientific ideologies.
