The problem is that those peer-reviewed finding are oftentimes thrown out as new information comes along.
That's not at all the problem. One of the great strengths of science is that it uses all the information available to construct an increasingly accurate view of the universe. Our understanding of human history is well supported by evidence, and in broad principle is no more likely to be "thrown out" than are our beliefs about the orbit of the moon.
No one knows how long Man has been around - and for good reason.
Not to the exact day, but we do know approximately - and with very good reason (i.e. it is supported by a lot of evidence).
Whether Man has been on Earth for 6 thousand or 6 million years matters not a whit to my belief in the Bible.
You should reflect on why that is. Why do you believe something even though it contains statements purporting to be factual that are demonstrably untrue? You could certainly continue to believe parts of the bible but if you are at all intellectually honest, when faced with the evidence, you must reject the bible's claims that humans have only been around for 6,000 years.
I do suspect, however, that the quest to prove Man has been around far longer than the Bible indicates is to destroy faith in the message that God is making things right for us.
There's no such quest. Humans have been around far far longer than the bible says, and it is those who cling to the contrary belief who have an agenda, one which they are usually quite open about.
How long? is the cry that resounds throughout the ages. What better way to make it seem as if God doesn't care than to cast doubt on the length of our sojourn here?
The bible has no relevance to science whatsoever. The purpose of science is to find out the truth about the nature of the universe and various aspects thereof. Whether the realities that are discovered correspond to what a tribe of nomads might have thought is utterly irrelevant.
