Now, let this imperfect summary of evidence in favor of the earth’s high antiquity be candidly weighed, and can any one think it strange that every man, who has carefully and extensively examined the rocks in their native beds, is entirely convinced of its validity? Men of all professions, and of diverse opinions concerning the Bible, have been geologists; but on this point they are unanimous, however they may differ as to other points in the science. Must we not, then, regard this fact as one of the settled principles of science? If so, who will hesitate to say that it ought to settle the interpretation of the first verse of Genesis, in favor of that meaning which allows an intervening period between the creation of matter and the creation of light? This is the grand point which I have aimed to establish; and, in conclusion, I beg leave to make a few remarks by way of inference.

First. This interpretation of Genesis is entirely sufficient to remove all apparent collision between geology and revelation. It gives the geologist full scope for his largest speculations concerning the age of the world. It permits him to maintain that its first condition was as unlike to the present as possible, and allows him time enough for all the changes of mineral constitution and organic life which its strata reveal. It supposes that all these are passed over in silence by the sacred writers, because irrelevant to the object of revelation, but full of interest and instruction to the men of science, who should afterwards take pleasure in exploring the works of God.

It supposes the six days’ work of creation to have been confined entirely to the fitting up the world in its present condition, and furnishing it with its present inhabitants. Thus, while it gives the widest scope to the geologist, it does not encroach upon the literalities of the Bible; and hence it is not strange that it should be almost universally adopted by geologists as well as by many eminent divines.

I would not forget to notice in this connection, however, a recent proposed extension of this interpretation by Dr. John Pye Smith, founded on the principle already illustrated, that the sacred writers adapted their language to the state of knowledge among the Jews. By the term earth, in Genesis, he supposes, was designed not the whole terraqueous globe, but “the part of our world which God was adapting for the dwelling-place of man and animals connected with him.” And the narrative of the six days’ work is a description adapted to the ideas and capacities of mankind in the earliest ages, of a series of operations, by which the Being of omnipotent wisdom and goodness adjusted and furnished, not the earth generally, but, as the particular subject under consideration here, a PORTION of its surface for most glorious purposes. This portion of the earth he conceives to have been a large part of Asia, lying between the Caucasian ridge, the Caspian Sea and Tartary on the north, the Persian and Indian Seas on the south, and the high mountain ridges which run at considerable distance on their eastern and western flanks. This region was first, by atmospheric and geological causes of previous operation, under the will of the Almighty, brought into a condition of superficial ruin, or some kind of general disorder, probably by volcanic agency; it was submerged, covered with fogs and clouds, and subsequently elevated, and the atmosphere, by the fourth day, rendered pellucid.—Script. and Geol. p. 275, 2d edit.

Without professing to adopt fully this view of my learned and venerable friend, I cannot but remark, that it explains one or two difficulties on this subject, which I shall more fully explain farther on. One is, the difficulty of conceiving how the inferior animals could have been distributed to their present places of residence from a single centre of creation without a miracle. Certain it is, that, as the climate and position of land and water now are, they could not thus migrate without certain destruction to many of them. But by this theory they might have been created within the districts which they now occupy.

Another difficulty solved by this theory is, that several hundred species of animals, that were created long before man, as their remains found in the tertiary strata show, still survive, and there is no evidence that they ever became extinct; nor need they have been destroyed and recreated, if Dr. Smith’s theory be true. Nevertheless, it does not appear to me essential to a satisfactory reconciliation of geology and revelation, that we should adopt it. But coming from such high authority, and sustained as it is by powerful arguments, it commends itself to our candid examination.

Secondly. I remark, that it is not necessary that we should be perfectly sure that the method which has been described, or any other, of bringing geology into harmony with the Bible, is infallibly true. It is only necessary that it should be sustained by probable evidence; that it should fairly meet the geological difficulty on the one hand, and do no violence to the language or spirit of the Bible on the other. This is sufficient, surely, to satisfy every philosophical mind, that there is no collision between geology and revelation. But should it appear hereafter, either from the discoveries of the geologist or the philologist, that our views must be somewhat modified, it would not show that the previous views had been insufficient to harmonize the two subjects; but only that here, as in every other department of human knowledge, perfection is not attained, except by long-continued efforts.

I make these remarks, because it is well known that other modes, besides that which I have defended, have been proposed to accomplish the same object; and it is probable that, even to this day, one or two of these modes may be defended, although the general opinion of geologists is in favor of that which I have exhibited.

Some, for instance, have supposed that the fossiliferous strata may all have been deposited in the sixteen hundred years between the creation and the deluge, and by that catastrophe have been lifted out of the ocean. Others have imagined them all produced by that event. But the most plausible theory regards the six days of creation as periods of great, though indefinite length, during which all the changes exhibited by the strata of rocks took place. The arguments in defence of this view are the following: 1. The word day is often used in Scripture to express a period of indefinite length. (Luke xvii. 24. John viii. 56. Job xiv. 6.) 2. The sun, moon, and stars were not created till the fourth day; so that the revolution of the earth on its axis, in twenty-four hours, may not have existed previously, and the light and darkness that alternated may have had reference to some other standard. 3. The Sabbath, or seventh day, in which God rested from his work, has not yet terminated; and there is reason to suppose the demiurgic days may have been at least of equal length. 4. This interpretation corresponds remarkably with the traditional cosmogonies of some heathen nations, as the ancient Etruscans and modern Hindoos; and it was also adopted by Philo and other Jewish writers. 5. The order of creation, as described in Genesis, corresponds to that developed by geology. This order, according to Cuvier and Professor Jameson, is as follows: 1. The earth was covered with the sea without inhabitants. 2. Plants were created on the third day, and are found abundantly in the coal measures. 3. On the fifth day, the inhabitants of the waters, then flying things, then great reptiles, and then mammiferous animals, were created. 4. On the sixth day, man was created.

The following are the objections to this interpretation: 1. The word day is not used figuratively in other places of Genesis, (unless perhaps Gen. ii. 4,) though it is sometimes so used in other parts of Scripture. 2. In the fourth commandment, where the days of creation are referred to, (Exod. xx. 9, 10, 11,) no one can doubt but that the six days of labor and the Sabbath, spoken of in the ninth and tenth verses, are literal days. By what rule of interpretation can the same word in the next verse be made to mean indefinite periods? 3. From Gen. ii. 5, compared with Gen. i. 11, 12, it seems that it had not rained on the earth till the third day—a fact altogether probable if the days were of twenty-four hours, but absurd if they were long periods. 4. Such a meaning is forced and unnatural, and, therefore, not to be adopted without urgent necessity. 5. This hypothesis assumes that Moses describes the creation of all the animals and plants that have ever lived on the globe. But geology decides that the species now living, since they are not found in the rocks any lower down than man is, (with a few exceptions,) could not have been contemporaries with those in the rocks, but must have been created when man was; that is, on the sixth day. Of such a creation no mention is made in Genesis. The inference is, that Moses does not describe the creation of the existing races, but only of those that lived thousands of years earlier, and whose existence was scarcely suspected till modern times. Who will admit such an absurdity? If any one takes the ground that the existing races were created with the fossil ones, on the third and fifth days, then he must show, what no one can, why the remains of the former are not found mixed with the latter. 6. Though there is a general resemblance between the order of creation, as described in Genesis and by geology, yet when we look at the details of the creation of the organic world, as required by this hypothesis, we find manifest discrepancy, instead of the coincidence asserted by some distinguished advocates of these views. Thus the Bible represents plants only to have been created on the third day, and animals not till the fifth; and hence, at least, the lower half of the fossiliferous rocks ought to contain nothing but vegetables. Whereas, in fact, the lower half of these rocks, all below the carboniferous, although abounding in animals, contain scarcely any plants, and those in the lowest strata, fucoids, or sea-weeds. But the Mosaic account of the third day’s work evidently describes flowering and seed-bearing plants, not flowerless and seedless algæ. Again: reptiles are described in Genesis as created on the fifth day; but reptilia and batrachians existed as early as the time when the lower carboniferous, and even old red sandstone strata, were in a course of deposition, as their tracks on those rocks in Nova Scotia and Pennsylvania evince. In short, if we maintain that Moses describes fossil as well as living species, we find discrepancy, instead of correspondence, between his order of creation and that of geology. But admit that he describes only existing species, and all difficulties vanish.
