Comparison of various Biblical theories on the age of the earth

I have read that according to Biblical references the age of earth is 6000 years. Even if you quote Young Earth Creationism, they too, will give a number no more than 10,000 years old. But in different belief systems like Hinduism, the age of the earth is comparable to that arrived to by contemporary scientific cosmology. Doesn't this imply that the Bible isn't perfect at all? **Can you compare various Biblical theories on the age of the earth?**
