“We therefore learn that periods of time for the Creation may have lasted 24 hours each, 1,000 years, or even millions of years. The periods of time are indeterminate in length; as one phase of the creation was finished, the next began. Therefore the age of the earth before Adam and Eve could have been great indeed.”
