The following quote comes from a sermon given by Brigham Young; what is rather interesting from this quote is that Brigham is open to the earth being “old” and states that God did not reveal whether Genesis 1 is to be interpreted a literal six-day creation, etc:
As for the Bible account of the creation we may say that the Lord gave it to Moses, or rather Moses obtained the history and traditions of the fathers, and from these picked out what he considered necessary, and that account has been handed down from age to age, and we have got it, no matter whether it is correct or not, and whether the Lord found the earth empty and void, whether he made it out of nothing or out of the rude elements; or whether he made it in six days or in as many millions of years, is and will remain a matter of speculation in the minds of men unless he give revelation on the subject. If we understood the process of creation there would be no mystery about it, it would be all reasonable and plain, for there is no mystery except to the ignorant. This we know by what we have learned naturally since we have had a being on the earth. We can now take a hymn book and read its contents; but if we had never learned our letters and knew nothing about type or paper or their uses, and should take up a book and look at it, it would be a great mystery; and still more so would it be to see a person read line after line, and give expression therefrom to the sentiments of himself or others. But this is no mystery to us now, because we have learned our letters, and then learned to place those letters into syllables, the syllables into words, and the words into sentences. (JOD 14:116 | May 14, 1871, emphasis added)
