Cheesecake. Is it cake or pie or something else altogether? Why is it called cheesecake?

I would say it is closer to pie than to cake, though it's obviously got distinctions from both. I think is called cheesecake because cheesepie sounds like a pie filled with cheese, but cheesecake indicates a cheesy cake, which sounds awful. The incongruency of the two things resolves into a sweet dessert that contains cream cheese (not first cheese most people would think of).

You thoughts?

I don't really know its a cake but at the same time its a pie. I think that it would be best not to think to hard about it cause someone might steal your cheesecake if your thinking about it to much lol.
