It's cute to call it "proto" science fiction ("prescience"?), but much of recent science fiction doesn't have much to do with science. Some is engineering or technology fiction.

Technology is old. I think weaving (as in cloth) might be oldest - I don't count dogs, olives or fire as they were domesticated, not created.

Blades are the oldest technology we have evidence of, iiuc.

You're right. Weaves wouldn't leave evidence, though the progression of rock, pointier rock, knapping seems easier than the leap of weaving, anyway - I'd guess it came about 70,000 years ago with the cultural explosion of cognition.

Sharp rocks go back 2 million :)
