Math and the Bible

I’d like to mathematically disprove Creationism, using the Bible.

By the most liberal estimates, the Bible describes 10,000 years of history. Most put it under 6 thousand, but we’ll give the benefit of the doubt. In 2 Peter 3:8, we find: “But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.” So I did the math:

10,000 God Years x 365.24 Days/Year = 3,652,400 God Days
3,652,400 God Days x 1000 Human Years/God Days = 3,652,400,000 (3.65 billion) Human Years

The Earth is over 4 billion years old, not to mention the universe being much, much older. Even with metaphors, the Bible is a joke.
