To The Edge of the World (fourth letter)

If you were here before I existed, I’m pretty sure you’ll be here when I’m gone — but I still don’t know where here or there is.
Perhaps all we have to guide us are recorded arrangements of alphabets.
I’ve written to the First People on Earth, which is pretty ridiculous… They probably didn’t have any form of writing, and besides, I still don’t know how to get the letter to them anyway.
Before the written word then, perhaps, the World was without end.
You couldn’t possibly exist. ┬áCan you know this from where you are now? Did the First Peoples?
