Show me a cat that isn't a Felidae, despite the myriad of "breeds" that exist??????
Show me a dog that isn't a Canidae, despite the myriad of "breeds" that exist?
Show me an E. coli that isn't an E. coli, despite the myriad "strains" that exist?
I think it is you that confuses the same species with
other species.
Just the tip of the proverbial iceberg is all.
If you're unwilling to accept categorization of different species, and have no problem changing goalposts between species and family (several steps apart), then let's look at this from a purely genetic standpoint.
Humans and certain apes share 96% of the same genetic code, with chimps it's 90%, with mice, 88%, with cows, 85%, with dogs, 84%, with zebra fish, 74%, with platypi, 69%, with chicken, 65%, with fruit flies, 47%, with honey bees, 44%, with round worms, 38%, with wine grapes, 24%, and with yeast 18%.
If I were to say to you, that which shares 96% of human DNA is the same as that which shares 88% percent of human DNA, that would be something like what you're saying. 'Show me a human that isn't a human'.
The facts are these. From apes, through the various species that came after them, but before modern homo-sapiens, the gene commonality between them and homo sapiens increases with time. In otherwords, as certain apes genetic code (but not all apes') changed to bring Sahelanthropus, and certain Sahelanthropus (but not all Sahelanthropus) changed to bring Aripithicus, the same to the Austrelopithicines, to Homo Habilis, branching to Homo Erectus, branching to Homo denisova, Homo floresiensis and Homo neanderthalensis, and other isolated groups of Homo heidelbergensis, Homo rhodesiensis and Homo antecessor coming together, interbreeding, leading to the evolution of small groups of early Homo Sapiens who interbred with the most modern Neanderthals and possibly Denisovans, leading to further increased gene pools, leading to eventual brain mutations that led to the extinction of other human species because of the arrival of us, Homo Sapiens Sapiens, there is an increase in the genetic commonalities. As time progressed, homonid genes became more and more like anatomically modern humans'.
Some of these species in close geological layers look very similar, but others in further apart geological layers look much more different. Those closer to the geological columns of the earliest apes look more like apes, those closer to today look more like humans. And ape skeletons, geologically, in layers, come before Homo Erectus, who come before Homo Sapiens, etc. So we know that humans didn't exist at the time of the first apes.
I challenge you to explain all that with a 6000 year old Earth and a creation model wherein only days separate humans and apes.
Not even all humans share the same genetic code. We classify humans in one species because we are sufficiently similar in physical characteristics to be grouped as a similar species able to breed with one another, but our code is on average around 99.5%, with similar races in similar geographical locations sharing more similar genes than different races on different continents.
Chinese share a considerably larger amount of their genetic code with Desonivans than European Caucasians, who share a considerably larger amount with Neanderthals than African natives. Our intelligence is varied, our genes, antibodies, immunities are varied, our intelligence, at least academically, is varied. We are all unique and ever evolving and changing.
Look at the growth in human intelligence in only the last 200 or so years. We generally don't run around burning witches any-more, yet in the til-recently-isolated gene pools of New Guinea, a practically lawless state, many humans still run around burning witches.
