While Enheduanna is the first known named poet, and the first known writer to use the first-person perspective in literature, earlier forms of written poetry exist with unknown authors.

For example, the author of the Epic of Gilgamesh, one of the oldest surviving literary works, remains anonymous.

She also composed multiple hymns for religious and political purposes, about devotion, spiritual conflict, and identity.

She then used her religious hymns to help consolidate her father's power by unifying the city-states of the empire and the people's beliefs.

They were that great.

Her poems were mostly dedicated to Inanna (also known as Ishtar), the Sumerian goddess of love, war, and fertility.

So our first named poet wrote about faith, exile, grief, emotional struggle, and personal resilience, as she was exiled from her position as high priestess by a usurper.

To answer my own question, I found out the first person in history known by name to have written poetry is Enheduanna, a Sumerian high priestess who lived around 2300 BCE in the city of Ur (currently Iraq).

She was the daughter of a king, so a princess, a priestess, and a poet.

YESSSSS

When and how we remember, what is it like? It's like time travel.

We don't just see a moment; we step back into it, transported back to a specific time and place.

This isn't just about looking backward. This personal time travel brings the past forward to shape who we are now.

Perhaps there was never a ready-take-out love with a "premade" someone, and you always needed to develop and nurture those feelings with people compatible with you, for as long as you want, for as long as you can.
And if you only do it once? Then that's it.

On the other hand, what if there isn't a single person perfectly made for another individual
since people grow
and change
and experience different things throughout life?

Would they still love the you from yesterday?
Will they still love the you from tomorrow?

But if you get to meet them, sure. It must be nice.
Lovely concept of true love as a once-in-a-lifetime event.

If you meet them, that is.

I mean,
what are the chances, really?

Would there be some kind of sign to tell you that they're gone, that you missed your one and only chance to love and be loved? Colorblindness, feeling of a void in your heart? A sudden excruciating pain, one you cannot ignore, so you'll just know when they are no more? Painful and stress-inducing.

Then what would happen if one of you died before meeting each other? Is the remaining one fated to live alone for the rest of their life? It seems lonely and unfair.

... But life is unfair, isn't it?

There are around 8 billion people on this planet right now, how would you meet them? How would you recognize them as your soulmate? What would guarantee that this special person even lives near you, or is even the same age as you? How far would you go to find them? Would they go to such length?

What if I couldn't return to my original world?
What if the door, tunnel, hole, dream, mirror, or even her, disappeared forever?
I would miss my old life and the people I left behind. I'd be left with the memories, only.

Why wouldn't she swap back our worlds? What would I have to do to switch back?

What if I ended up in a world much worse than my own? If our lives were too different, it would be like getting myself into an entirely new world, although essentially the same.

Of course, some instructions could be helpful during the swap. But... What could make her so eager to switch worlds?

Or, I could go to escape, run away from my current life. Am I unhappy with my current life? What could bother me to the point of switching worlds?

On the other hand, why would she switch lives? Curiousness? Also running away? Envy? How well can she mimic my life?

I could go by curiosity, to see what it would be like to live a different life. For a day or two, maybe a whole week? Like a vacation, I would be a tourist in an alternate life.
What is the weather like? How do people treat me as my other self? How well can I mimic her life?
