Thanks to modern science, we now know more about religious history than ever: Scientific archaeology began in the 18th century, and since then excavators have been discovering and interpreting evidence, ranging from tiny goddess figurines carved from mammoth ivory to entire sacred landscapes, such as at the Giza plateau in Egypt. The archeological evidence enhances and corrects our knowledge derived from books and other preserved objects. Ancient graves, statues, temples, stones, sacrificial offerings, or places of initiation - they all express the universal human search for spiritual power and understanding. Archaeology provides evidence that is very different from historical writings like the Bible or the Vedas. Modern technology enables us to find more places than ever, and unlock their secrets like never before. With airplanes, satellites, or underground radar, archaeologists find lost temples and other cult sites. And with advanced scientific and medical techniques, they can analyze the residues left by funeral feasts, or the last meals of sacrificial victims. They can reconstruct medical histories, or genetically trace the journeys of ancient people.

The millennia of human experience that preceded the invention of writing about 5,000 years ago is only accessible to us through archaeology. Some 30,000 years before the first religious writings were made, Ice Age peoples of Europe and the Near East were creating shrines in caves, modeling images of divinities and shamans, and using art and music in ceremonies. Even earlier, in the time of the Neanderthals, some of the tribe’s deceased were buried with flowers, possibly symbolizing resurrection after death.

What do we learn from archaeological discoveries about religion? We discover that religious practices occupy a central place in most cultures and civilizations. It seems that religious belief is deeply embedded into human consciousness. Religion appears in specific manifestations across widely separated times and places. Mystical meaning is assigned to caves; earth mounds are erected, megaliths are carved, and pyramids are built as gateways for the afterlife. Sacred enclosures like temples, and even whole landscapes like valleys or mountains, serve as places that allow a special connection to the heavens, or as the endpoints of journeys that open the mind to religious experiences. Many civilizations developed rituals for the burial of the dead; human sacrifices are wide-spread, and elaborate rituals are developed in order to honor the rulers. Across cultures, temples are housing images of gods; and religious specialists like shamans or priests exist everywhere. Ancient traditions outlive the religions from which they originated - they are woven into the fabric of later religious experience, art, and traditions. Archaeology shows how religion exists at the core of every society’s perception of its own identity.
