Is Moonbeam a layer 1?

Excuse me, but could you clarify something for me? I've been hearing a lot about Moonbeam, and I'm curious if it's considered a layer 1 blockchain solution. Could you elaborate on that, please? I'm trying to get a better understanding of how Moonbeam fits into the broader blockchain ecosystem, and if it's more akin to a foundational layer like Ethereum or a layer 2 solution built on top of another blockchain. Thank you for your time.
