The answer depends on what You are trying to prove.
If You define this poem as ordered list of words that can be interpreted trough cultural and local context, then it existed even before it was written down.
If You want to go more realistic way then this poem exists only through my memory (partly as memory and partly as an emotional association) and will disappear with my demise.
