Does Gelato have eggs?

I'm curious, does the dessert known as Gelato contain any eggs in its ingredients? It's often compared to ice cream, but I've heard differing opinions on its egg content. Some say it's similar to the Italian tradition of custard-based gelato, which would suggest the presence of eggs, while others claim it's a simpler, creamier version without the addition of eggs. Can you clarify the situation for me? Is there a definitive answer to whether Gelato contains eggs or not?
