Is it this simple to prove the bible inaccurate?

[jek187]

The Bible says mankind is ~5,000 years old. However, they have found evidence of a settlement in Chile that is 12,000-12,500 years old, and projective points in North America that are 11,000 years old. National Geographic talking about 12k year old settlement and projectile points

I realize this argument comes up with dinosaurs and geological issues, dealing with the earth being millions or billions of years old. People normally defend the Bible by saying that the 1st week was extra long. This does not apply here. (Since Adam did not start breeding until after Creation Week.)

What defense do Bible believers have for this? This seems like such a blatant error, that I must be missing some key defense.
