Is Ethereum built on Cosmos?

I'm curious about the relationship between Ethereum and Cosmos. Could you clarify whether Ethereum is built on Cosmos? I've heard some people mention this, but I'm not entirely sure about the details. I understand that both Ethereum and Cosmos are blockchain platforms, but I'm not sure if they are interconnected or if Ethereum simply utilizes some of the technologies or principles developed by Cosmos. Could you elaborate on this point and provide some insights into the relationship between these two platforms?
