Nicoleisms on Easter

My six year old is really quite confused about Easter. I'm an atheist (though not in an uppity better-than-you way. More of a I'm-too-lazy-to-care-about-this way) and my husband calls himself Christian, but let's call it agnostic for accuracy's sake. Point being we've never properly explained Easter besides "hey, it's that time of year we color eggs and a bunny hides them."
So a little while ago I was at the sears optical waiting to get my glasses and Nicole picks up a Highlights magazine and wants to read it to me and there's a big article on Easter in there. It sounded something like this "For Christians Easter is one of the most important religious celebrations of the year. This holiday marks the day that Christians believe that Jesus Christ rose from the dead??? It is knows as the Resurrection." Pause here for the oddest look from her, then continues:
"To celebrate Easter people will take part in the same celebrations. Eggs, for example, represent new life and the Resurrection..." where she then stops reading, as if giving up on this article ever making sense, and flips to something sensible. Ah, hidden picture. That's better.
Since then she has been asking questions here or there that I have a hard time answering. Maybe I should send her off to church, but I know churches don't really like it when it's just the kid and no parents. I know this having done it all throughout my childhood.
Anyway, today it gets better. She asked me "Why do we call it Easter when it's about this guy" "His name is Jesus, honey" "When it's about Jesus coming back from the dead? Shouldn't we just call it Jesus popping out from his grave day? And it's silly because if he was dead how did he come back? He couldn't have done that?? And why do we color eggs and have a bunny hide them?" Those are great points, Nicole. I have no idea. Not a clue. Instead I was laughing my ass off while she looked at me confusedly "what's so funny mommy?" She wants an answer Uh, nothing. You have a good point, sweetie. I have no idea. You'll have to ask someone who knows.
Poor Nicole is already confused about death. My grandpa passed a couple of years ago and just before that we went to the hospital to visit him. She was 4 at the time, but she remembers and insists we visited him at the post office which has given her a really odd obsession with post offices. I think the most confusing part for her is that we can't see him anymore. I try to explain, but she just says "we can just dig him up and see him" Uhhhh. Hmmm...No? How do I explain decay? That seems too traumatic. More to the point I sort of fibbed and told her he was buried instead of telling her he was actually cremated because trying to explain that would have been more difficult. "Well honey. See they put his body in a hot hot fire and burn it up until it's ashes" seemed an unnecessary detail to me. So this whole learning about Jesus coming up from the dead like some holy zombie is really just baffling for her and she's having a hard time understanding it and how that dammed bunny and his eggs fit in. I'm sure if daddy was here he could probably explain this in a totally non sacrilegious way, but I can't.
