Hunter-gatherer peoples during the Paleolithic period lived nomadic lifestyles, following animals as they migrated and seeking shelter in caves during winter. They survived through hunting and gathering fruits, fish, and other animals. Tribal societies consisted of 20-30 people, with some individuals like strong warriors or elders having more influence. Paleolithic peoples invented basic stone tools for hunting and crafts. They also controlled fire starting around 1.5 million years ago, which provided warmth, light, and facilitated social gatherings. Spiritual beliefs included venerating natural elements and performing burial rituals that suggested a belief in an afterlife. Some of the earliest artworks also emerged in the form of portable figurines.
