Is Aptos part of Meta?

Excuse me, could you clarify something for me? I've been hearing a lot about Aptos recently and I'm trying to understand its relationship with Meta. Is Aptos actually a part of Meta? Or are they separate entities? I'm a bit confused about this, and I'd really appreciate it if you could help me clear up this matter. I'm particularly interested in understanding the business structure and affiliations in this area of cryptocurrency and finance. Could you provide a bit of clarity, please?
