Early ICR scientists hypothesized that the “waters which were above the firmament”¹ implied a canopy of water vapor that covered the earth before the Flood. However, later tests led researchers away from this model. What changed their minds?

When visitors inspect ICR’s seven-and-a-half-foot-long model of Noah’s Ark, the dinosaur figurines on the bottom deck tend to catch their eyes. They often ask about those dinosaurs, giving our tour guides a chance to explain how dinosaurs fit in biblical history.

Many who study Genesis show intense curiosity about the pre-Flood world. But “the world that then existed perished, being flooded with water,” so little physical evidence remains.¹ Reconstructing the pre-Flood world is like building a puzzle after all its pieces were run through a blender. However, Genesis gives us a good start.
