No - this is about evidence.
You said:
It's a foregone conclusion that it is accepted in the Bible Belt that we all descend from a common ancestor.
As the evidence shows, Neanderthals are a humanoid species that are genetically different to us.
Humans living before the time of Adam and Eve had sex with a different human species who subsequently contributed about 1-4% of the genomes of non-African modern humans.
This is a fact you can't argue with.
If you do, you are exactly the same as flat earthers who deny the evidence that is before them.
