Earth's Magnetic Shield Is Vanishing

How old is the earth? Billions of years or just thousands of years?

In the StarTrek series the starship Enterprise had invisible shields to protect it. The earth has a real invisible shield, our magnetic field, that protects us from intense, harmful radiation from the sun. Without it, life on earth could not exist. But earth's magnetic field is decreasing, wearing down so quickly that we know the earth could not be more than 20,000 years old.

Where Does Our Magnetic Field Come From?

The iron core of the earth creates a magnetic field. This magnetic field must be strong enough to deflect radiation from the sun, but not too strong. Analysis of the magnetic field, and it's rate of decline, shows that the earth cannot be more than 20,000 years old. That's a maximum number that is consistent with the Biblical time scale of the earth being created 6,000 years ago.
