If I had only Scripture to judge by I would assume it is a young Earth. If I had only science to judge by I would assume it is an old Earth. I know that the two can be reconciled but I'm not entirely convinced either way. I probably lean toward the young Earth in the belief that the assumptions guiding the testing of the Earth's age may be faulty (e.g. uniform rate of decay).
