Easter falls nicely in the same time as the pagan dertility festivals, indeed. Although the Christian Easter is somewhat different, but it does reflect other ancient rituals. In many ways (from a Christian point of view) it has the same message as the Jewish Easter (God leading his people out of bondage, the Jewish one in Egypt, the Christian one from that of sin), but when you don't have any notion or interest in a concept such as sin or a higher authority you may have to answer to, it's fairly useless to discuss the whole matter.
Only when you are kind of open minded you may be able to grasp the matter, but that goes for everything in life.
