Is Tezos based on Ethereum?

Could you please clarify for me if Tezos is indeed founded on the Ethereum blockchain? I've heard some rumors about its technological similarities, but I'm not quite sure if there's a direct dependency or if it's merely a case of two projects sharing certain conceptual ideas. I'm interested in understanding the relationship between these two cryptocurrencies, especially in terms of their technological frameworks and design principles. Could you elaborate on this point for me? It would greatly assist me in grasping the nuances of the cryptocurrency landscape. Thank you for your time and consideration.
