63:5.4

These aborigines of Urantia were not tree dwellers, though in emergencies they still betook themselves to the treetops. They regularly dwelt under the shelter of overhanging cliffs along the rivers and in hillside grottoes which afforded a good view of the approaches and sheltered them from the elements. They could thus enjoy the comfort of their fires without being too much inconvenienced by the smoke. They were not really cave dwellers either, though in subsequent times the later ice sheets came farther south and drove their descendants to the caves. They preferred to camp near the edge of a forest and beside a stream.
