Why Not Noah’s Cave
Why was Noah instructed to build a ship? Aren’t there other means of surviving a 15 cubit global deluge and 100% humidity? Since we now know the floodwaters did not cover the mountaintops, a cave high in the mountains may have worked to save Noah, his family, and animals. Why build a ship?
Assuming mountains in Noah’s area were suitable for tunneling, a Noah’s ship-sized cave would have been possible. However, cracks and fissures might have gushed water and poisonous gases into the cave during the flood event. Yet, even if they did not, Noah would have worked much harder on a cave. The cave would have been spread out to 300 x 100 cubits unless he made his cave multiple stories with wooden floors. Support for the overhead of the cave would have been necessary. So now, he is cutting a cave into stone and building a wooden structure inside the cave as well. On a wooden hull ship, the outer planks provide some insulation from cold. A cave’s walls would not provide insulation yet he could have lined the cave everywhere with wood. Had this been Noah’s original plan, he has essentially built a ship inside a manually hewn cave. Had Noah survived by tunneling into the side of a mountain the question might now be “Why not build a ship?” Look how much easier it would have been!
