Why do most languages sequence names from first to last?

Not sure about other languages, but Russians are more likely to give their name as FIO, familia imya and then ochestvo (family name, given name, and then patronymic), especially in official settings. I'm given to understand the practice was even more common in Soviet and Tsarist Russia.

And if you'll forgive me for being a little sassy, tautologically, all languages present names from first to last.

It's mostly because "that's how the ancestors did it". In many parts of Europe, the system for last names used to be (and still is in some places) something like "son of [father's name]", which wouldn't really make sense to put first in speech. In other cases, things like place names or occupations were used to identify someone, so something like "George the Smith", which would only slowly be formalized into family names and become "George Smith" in the middle ages. The word order was just kept as it was. On the other hand, in China, family names were introduced by imperial decree about 2000 years ago, to facilitate census data and bureaucracy. For that purpose, it makes sense to put them first, as that's how you do it when organizing them into a table. That Chinese practice would have spread to other parts of Asia etc.

It's all about historical convention. And countries can even use both. For example in Portugal, we use Name, Surname exclusively on day-to-day, but when dealing with government institutions we often use Surname, Name.

And as other comments say in Russia they have even more conventions based on the context.

To add to this, in Western Europe the name order was formalized by decree during the Napoleonic era. The Napoleonic reforms had long-lasting influence and impact, and it became the established standard in western Europe.

I always smile when I think of a fictional quote on this. The Asian name order chatacter said:
"So individuals are more important than their family?"
And I believe the only way to go is the Asian name order. And using my name in reverse is not natural.
Tho don't get me started on the US date format. I always mess up month/day. Why is it reversed??
Year-Month-Day is the way to go.

Convenience, one would suppose

Very much this.

Today, the more English-like way of listing first name first, last name last in a context where the Western influence is just stronger and more prevalent, like YouTube, social media at large, git commits, etc. I think I've also seen it on TV, but I haven't watched it for over a decade, really.

Generally, it seems like this order is become more and more popular thanks to globalization. which I actually like, but yeah, the more official something is, the more likely the traditional order is to appear.

That said, I think for the Russia-speaking context, last name first seems to be better in some cases, because the first names are not as varied.

Year-Month-Day is the way to go.

ISO 8601 is the way!

not really answering but because of this difference and my asian background i keep confusing first name/last name in english. lmao

Name conventions can be a bit more diverse than you might think.
