When I first began to consider this topic, the 1st person I read to understand was Dr. J Vernon Magee. He was a proponent of the "Gap" theory.
The gap theory is the view that God created a fully functional earth with all animals, including the dinosaurs and other creatures we know only from the fossil record. Then, the theory goes, something happened to destroy the earth completely—most likely the fall of Satan to earth—so that the planet became without form and void. At this point, God started all over again, recreating the earth in its paradise form as further described in Genesis. The gap theory, which is distinct from theistic evolution and the day-age theory is also called old-earth creationism, gap creationism, and the ruin-reconstruction theory.
God created the heavens and the earth. Then verse 2 begins a detailed breakdown of the step-by-step process that verse 1 summarizes. However, the statement that “the earth was formless and empty, and darkness was over the surface of the waters” vs #2.
This is puzzling because the Creation process had not begun but there was WATER on the earth! The idea that God created a useless and shapeless earth is an uncomfortable position for some conservative theologians, and this leads them to the gap theory, or an old-earth perspective.
For me...........I do not know. What I am sure of is that Adam and Eve did not live with dinosaurs. I
am only posing speculations and asking questions.
