The Bunny or the Egg?

According to Wiki, Easter eggs are specially decorated eggs given to celebrate the Easter holiday or springtime.

The egg was a symbol of the rebirth of the earth in Pagan celebrations of spring and was adopted by early Christians as a symbol of the rebirth.

The ancient Persians painted eggs for Nowrooz, their New Year celebration, which falls on the Spring equinox. The Nawrooz tradition has existed for at least 2,500 years.
