Do eggs go bad if not refrigerated?

Excuse me, I was wondering if you could clarify something for me regarding the storage of eggs. The question is, do eggs actually spoil or go bad if they're not kept in the refrigerator? I've heard differing opinions on this and I'm curious to know the truth. Some people seem to think that it's perfectly fine to store eggs at room temperature, while others insist that refrigeration is necessary to prevent spoilage. Could you please shed some light on this matter for me?
