This may come as a shock to many people, but Jesus didn't write the Bible.

The Hebraic Bible was a collection of text that was held sacred by the people who occupied the land where Jesus was born.

A funny thing about the Hebraic Bible is that it appears that people were adding and removing text from the thing up until the Greeks at the Library of Alexandria translated the book into Greek making changes impossible.

The idea that the Bible says the earth is just 6,000 years old was put together by some pundit who made the questionable assumption that the genealogy listed in the Bible must be continuous and complete.

Even with modern tools, most people today have a hard time calculating their genealogy back a few generations.

Think about it. The person who made the 6000 year claim assumed that people in a per-literate society must have been able to keep a complete and continuous genealogy from before the invention of writing.

What people do is take a questionable interpretation of text that was written hundreds of years before Christ by some blowhard that came along some millennia after Christ to claim that Christ said the world was 6,000 years old.

Interestingly, the New Testament tells people to ignore the genealogies. Here are two quotes:

Titus 3:9 ESV

But avoid foolish controversies, genealogies, dissensions, and quarrels about the law, for they are unprofitable and worthless.

1 Timothy 1:4 ESV

Nor to devote themselves to myths and endless genealogies, which promote speculations rather than the stewardship from God that is by faith.

The Christian Bible actually says that these endless genealogies are a waste of time indicating that Christians and probably Christ-himself didn't put any store in the genealogies used to create the 6000 year old story.
