The skeptical might be reminded that these conditions, once understood by scientists, was used to explain how Asian peoples migrated to the “New World” across the so-called “Ice Bridge” that they believe connected Asia to the Alaskan Coast during the last Ice Age.
Later scholars have argued that this crossing was probably accomplished by boat rather than on foot across the frozen wastelands of Alaska. It would have been safer and permitted fishing for food. It would also explain why populations spread so quickly from Alaska to Tierra del Fuego at the tip of South America.
At any rate, the church was beautiful and the story captivating.
