"Such a conclusion is wholly uncalled for. The Bible record is in harmony with itself and with the teaching of nature. Of the first day employed in the work of creation is given the record, “The evening and the morning were the first day.” Genesis 1:5 . And the same in substance is said of each of the first six days of creation week. Each of these periods Inspiration declares to have been a day consisting of evening and morning, like every other day since that time. In regard to the work of creation itself the divine testimony is, “He spake, and it was done; He commanded, and it stood fast.” Psalm 33:9 . With Him who could thus call into existence unnumbered worlds, how long a time would be required for the evolution of the earth from chaos? In order to account for His works, must we do violence to His word? Ed 129.1"
"And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day."
EGW directly quotes Genesis 1:5 to support her argument about the creation days.
"For he spake, and it was done; he commanded, and it stood fast."
EGW directly quotes Psalm 33:9 to support her argument about the power of God's creation.
"It is true that remains found in the earth testify to the existence of men, animals, and plants much larger than any now known. These are regarded as proving the existence of vegetable and animal life prior to the time of the Mosaic record. But concerning these things Bible history furnishes ample explanation. Before the Flood the development of vegetable and animal life was immeasurably superior to that which has since been known. At the Flood the surface of the earth was broken up, marked changes took place, and in the re-formation of the earth's crust were preserved many evidences of the life previously existing. The vast forests buried in the earth at the time of the Flood, and since changed to coal, form the extensive coal fields, and yield the supplies of oil that minister to our comfort and convenience today. These things, as they are brought to light, are so many witnesses mutely testifying to the truth of the word of God. Ed 129.2"
"There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown."
EGW refers to larger men, animals, and plants found in the earth and connects them to the pre-flood world, which aligns with the mention of giants in Genesis 6:4. While not a direct quote, the theme of a different world before the flood is present.
