Christians believe that Jesus is God and that God knows all.
Since Jesus believed that Adam was the first man, Adam was truly the first man.
Now evolutionary biology and genetics show that the first man predated Adam by hundreds of thousands of years, the implications for the belief that Jesus is God are:
God doesn't really know all, or
Jesus was not God because he erred about Adam. His belief in Adam as the first man WOULD however be perfectly in line with first century Jewish beliefs.
