That was a long time ago. By the time you lost Bitcoin, you should immediately find the key to open the wallet. You can check all the places where you usually put your important things. There is a very low chance to found a lost Bitcoin private key if takes a decade before you decide to find it. Most of the time, the things that are visible in your house are not visible in today.
It's a lesson to us that we should keep our private key in a safe place, if possible in multiple places. If ever you can't find it, the chances of finding them increases and you should change your private key after you found it.
