Among the high mountain plains, rivers, streams, everything was present except for vast oceans. On its back, the mountains and rivers carried could accommodate billions of living creatures to survive and propagate, constructing a complete ecosystem with material circulation.
Mountain Sea Whale? World Whale?
Even though he personally witnessed the true form of this Ancient God-like creature, there was no narration or text to introduce it to Noah, so he could only name it based on its form and the characteristics of its displayed power.
However, Noah felt that calling it the Mountain Sea Whale was most appropriate, whereas naming it the World Whale seemed a bit exaggerated. Though this great whale was absurdly large, the ecosystem on its back didn't quite meet the standards of a complete material world.
It merely carried a piece of mountain and sea while moving, not supporting a whole world. A complete material world could nurture belief in Divine beings.
