Step 1 : Introduction to the question "What are Easter eggs said to symbolize?"
...Historians tend to lean toward the belief that the custom of Easter eggs is rooted in pagan traditions. The egg is an ancient symbol in many cultures and is almost universally taken as a symbol of new life. The egg is historically an integral part of pagan festivals celebrating the coming of spring. Because Easter is a Christian religion, Easter eggs take on a different symbolism for many. For those who follow a Christian belief, Easter eggs represent Jesus's emergence from the tomb and His resurrection. The practice of decorating eggs traces to the 13th century. Source: History.com
