Many extinct animals went extinct after a few millions of years of being present, often tens of millions.
The oldest technologies humans still marginallyand recreationally use (like the flintstone knives mentioned) are maybe 30k to 50k years old. There is no 1M years old human-specific technology, because anyone resembling humans barely existed that long ago. Only the very basic things likely were used, like smashing seashells with a rock — but it's a "technology" used to this day by apes and even birds.
If you had Googled "oldest flint tools" you would have found directly that you are extremely off.
> The oldest stone tools currently pre-date genus Homo, they were found in Kenya (Lake Turkana) and date to 3.3 million years ago.
And that's just what current archeology/paleontology has been able to find so far. The find for the 3.3 million years was 700k years earlier than the previous record. It's not a stretch of the imagination to think we will find even older artifacts.
After manipulating wood and metal (soldering) I became quite fascinated by how fragile everything is. And how some people aeons ago manage to make time to craft hunting tools with stones, wood and threads is astonishing. Let alone the mastery of using them. A weak spear or arrow has big impacts on your life.
