Is Solana based off Ethereum?

Could you clarify for me whether Solana is actually built upon the foundation of Ethereum? I've been hearing a lot about these two cryptocurrencies lately and I'm trying to wrap my head around the technicalities of their relationship. As I understand, Ethereum is a popular blockchain platform that enables the deployment of smart contracts and decentralized applications, while Solana is touted for its high scalability and speed. So, does Solana leverage any components or functionalities from Ethereum, or is it a completely independent blockchain? I'd really appreciate it if you could shed some light on this matter for me.
