How to write in Cuneiform

Good stuff, but this has triggered my pet peeve! The title should be:

    How to Write in Cuneiform, the Oldest Known Writing System in the World

The added word being: KNOWN

You can argue that, "well, obviously!" but correctness and exactness are what makes science, history, journalism, etc good, and allowing incorrectness like this is a step backwards.

I read a history book when I was a teenager (can't remember which one, unfortunately), and the author wrote a preface that said something along the lines of "Everything in this book is based on the published information I could discover during my research period of April to September 1999. I have chosen to write in absolutes--stating many things as certain and clear--but in reality there is still much we do not know about this time period. No history author should say their writing is fact and any good historian will make it clear that their work is composed of assumptions layered on assumptions. Please read these works with this in mind."

If you don't have a preface like that, you should add "known" to your title/sentence! I will argue with someone all day over this! I will die on this hill!

Sure, but you could also endlessly add clarifying details to be more exact

How to Write in Cuneiform, the Oldest Known (by the author) Writing System on Earth, the third planet from the Sun in the Milky Way galaxy, as of 2025 as long as you're a human without a major disability that would prevent you from using these techniques or are at least a being with similar hands and arms also able to obtain the necessary materials and can read and comprehend modern English if you aren't too busy doing other things and expect to live long enough to complete the task

You often get nitpickers going after some small technically correct detail which may be true but no reasonable person in the intended audience would ever actually need to be told. No one reading the original title would assume that the author had omniscient knowledge of the whole human history of writing beyond present archaeological fact and this doesn't need to be pointed out.
