Is Tezos built on Ethereum?

Could you please clarify something for me? I've been hearing a lot about Tezos recently and I'm trying to understand its technological foundation. Is Tezos, in fact, built on the Ethereum blockchain? Or does it have its own independent architecture? I'm interested in understanding the relationship between these two platforms, if any, and how it might impact the functionality and potential of Tezos. Could you provide some insight into this matter? Thank you in advance for your assistance.
