Bunnies and eggs are signs of fertility, which is associated with Spring.
That's a pagan influence. Easter isn't related to fertility.
I think that some of the problem in this thread is disagreement about what is being asked. Some are answering the question of whether Easter was created to imitate existing pagan holidays, and others are addressing European adornments which were added later.
I live in Mexico, and Easter, like Christmas, is a very different holiday that I remember in the States. For me, Easter was always about bunnies and eggs. We got chocolate rabbits that we bit the ears off of first, and hunted for eggs that we had died earlier in the week with Paas egg dying kits. Jesus and resurrections weren't a part of the celebration.
Then I moved to Mexico, now see a biblical Easter, and even participate a bit. On Palm Sunday, my wife and I have followed Jesus into Jerusalem over a path of flower petals carrying braided palm fronds:
This is what Good Friday looks like:
All one need do to see the pagan influence of Easter in America (and I presume much or most of Europe) is compare the two.
So, if the question is whether Easter was created in homage to surrounding pagan rituals and celebrations, probably not, although it appears to be a spin-off of Passover, which, being a celebration related to the Jews escaping captivity, is totally unrelated to Easter. But Easter has been transformed from a resurrection holiday into a fertility holiday in some parts of the world.
Incidentally, we see the same thing with Christmas. Whereas in the States, Christmas was a winter holiday that featured Santa and Frosty, tinsel and flocking, in Mexico, it's still a desert holiday featuring mangers and camels and magi and baby Jesus. I've been witnessing the transformation of the holiday as more and more Christmas lights are appearing on homes playing the wintery tune Jingle Bells, not Silent Night. And this is principally because a Wal-Mart opened up here about fifteen years ago, and carries the inventory of American Christmas. We've begun giving Christmas presents of candy and a little money to our neighborhood kids, something unfamiliar to them. They don't have a tree usually, or gifts under it, but check back in ten or twenty years.
And Halloween. I remember the first time kids came to the door saying, "Halloween!" rather than "Trick or treat," but they were in costumes of monsters and princesses, had plastic pumpkin buckets and were expecting candy, nothing like the native Dia de Muertos.
So, the pagans have reached Mexico via Europe, where fertility symbols were added, and Wal-Mart, where the pagan trappings are sold at everyday low prices.
