I would disagree with the charge of assumptions being at play as these are claims I am making are backed up with substantial evidence in the scientific community.
In order to understand better why I take the position assumptions are at play:
Our knowledge of Neanderthals is based on a limited number of remains and artifacts from which
we must make inferences about their biology, behavior, and relationship to ourselves.

The charge is not at you directly, I realize there is substantial evidence backing up evolution and millions of years, but rather my charge is that evidence involves a substantial amount of assumptions and conclusions. We are not on a solid foundation when discussing evolution or dating and alternative conclusions do have some merit. I have no problem with the theory of evolution, that it can explain the origin of the species is where it runs into trouble.
Exactly how this extinction happened we can only speculate on, but via the fossil record and genetic evidence we can speak quite confidently about the nature of the neanderthalensis and just how they came about.
We need to find where this piece of the puzzle fits in:

Neanderthals are the closest hominid relatives of modern humans, yet the assumptions of their age and intelligence gives them a growth rate of 5x to 12x that of humans, whereas chimps are 2x that of humans. An alternative explanation would put Neanderthals at the advanced ages talked about in Genesis.
I am however unable to be convinced of things for which there is no support and every reason to believe in the contrary, but if you feel you have some pertinent evidence that is compelling enough to overthrow all of modern biology, then I would like to hear it.
That seems a fallacious appeal to authority, nobody is trying to overthrow biology. If anything, a strictly materialistic approach to science is what is being overthrown. Intelligent design theory offers some very compelling evidence, there are a few other threads about it in this forum if you are interested.
Not sure why this would be the chief concern of yours, if I attempted to speak to the origin of language it would only be speculative though I can say that it was more recent and only occurred with Homo sapiens as we are the only hominid with a brain developed enough to have that capacity.
I commend your commitment to truth, very refreshing to see such an honest answer. The reason this is a chief concern of mine is there is no evidence language is the inevitable result of brain size. Meaning, puberty is inevitable, communication is inevitable, language is not. There have been documented cases of feral children "who often seem mentally impaired and have almost
insurmountable trouble learning a human language."
Jill Bolte Taylor is a neurologist that lost language after a stroke, but regained it later. Her story offers insight to a world without language. Her world without language was completely stress free. She didn't think, she felt the world around her. She related to the world around her in a completely different way, without any contemplation. The way humans learn language actually transforms the synapses and organization of thoughts in our brains, and most importantly
gives us the ability of contemplation. Explaining the origin of language in humans cannot be dismissed easily. Language is extraordinary, completely foreign to an evolutionary explanation, but fits with a literal interpretation of Genesis.
