there is an uncertainty about my biological parents whereabouts but the status of them being alive or dead is unknown

I do BELIEVE that there is a chance that my birth parents maybe dead and may be berried at a cemetery out there somewhere marked by headstone or plaque or tombstone but if that is where my birth parents may be i will want to visit their graves and sit down by their graves and have a chat with them and talk to them and rest my hand on their graves and grave stone and say my goodbyes and walk away but there is also a chance they may be alive and well and living their best lives out there somewhere until then till all are one
