You don't "find out"
You will go back to being what you've been for the majority of the last 13.75 billion years. Do you remember what you were before you were born? No? Nor will you know anything after you die. Your atoms will exist forever, though. So you can look forward to being bits and bobs of all kinds of things, but you'll never know it.
