I'm sorry, but that's a strawman. It was common for genealogies to include only the "most significant" members of the lineage, with "significance" determined by the intent of the author recording the genealogy. One can see this illustrated by comparing overlapping genealogies from different portions of Scripture. Such an understanding is within the bounds of most current views of "inerrancy."...The Bible presents a line of people with dates of birth from Adam to Noah, to Jacob, to king David, to Jesus. If that is open to interpretation, the whole book is. If the flood took place in 3300 b.c., as Dr. TV Oommen suggests, the genealogy needs to be adjusted, the gap needs to be filled with people.

Now, I happen to believe in a literal Adam and Eve, and a literal Flood that destroyed all but 8 humans. I believe this because there are some rather important theological points in the NT that rely on this truth.
Since geneticists affirm that it is impossible for current humanity to have descended from a single pair of modern humans in any feasible time frame, or from a set of 8 (some of whom were related) even more recently, I understand that modern genetic science is incomplete or faulty. And since I understand that, I may as well believe the other sciences are similarly lacking, and take the earth as being extremely "young" compared to what standard science ***erts.
