Why in Genesis in the Bible it says, Their Lord could not find what he created after they sinned?

Someone can easily ask a question to which they know the answer. Usually, the reason to do that is to point something out or teach something. Obviously, Adam and Eve had sinned. God asked, "Adam, where are you?" Where was Adam? He was hiding from God. Adam's sin had destroyed his fellowship with the Lord. God knew this and He was pointing it out to Adam.
