Folks whose religious faith informs them that there have been only "10,000 years of existence" will never accept the answer to your question. This is because faith is unquestioning belief and acceptance without proof, whereas science is constant questioning, and a continual search for proof and knowledge. Religion and science are not incompatible except to religions wherein the teachings are rigidly fundamentalist.
A perfect example is found in those religions which teach that their adherents should not obtain medical help for illness or injury, but that one should only pray for whatever outcome God wills. Those religions are certainly entitled to their beliefs, but the rest of us are grateful for modern advances in medical science.
Similarly, religions which hold that the world is about 10,000 years old are perfectly entitled to their beliefs. The rest of us are grateful for scientific advances that enrich our knowledge of the grand sweep of earth and human history stretching billions of years into the past. God gave human beings brains capable of moving humanity from cave-dwellers to spacefarers in only about 100,000 years, and I, for one, think that's one of the most beautiful aspects of His creation.
“God gave human beings brains capable of moving humanity from cave-dwellers to spacefarers in only about 100,000”
Actually it is not until Christ that mankind advances - we were still cave dwelling at 0 AD.
