It's literally the scientific consensus. You thinking of a cartoon axe with a wedge-shape and an oak handle when you hear the word "axe" isn't my problem.

I've seen animals sharpen rocks, it's not that impressive. And pretty removed to just assume it was people 800,000 years early.

These hand axes are incredibly complex and it takes hundreds of hours to learn to make one. It is not my fault you're scientifically ignorant and still silly enough to think your childish notions are better than prevailing scientific notions.

Here's some proof of earliest structural use of wood at least 476,000 years ago. And that doesn't mean piling sticks together, it means actual woodworking, joinery.

When you're in biology class and you see an image of an egg cell, do you start flailing around saying "that's not an egg, that's a picture of a slimy circle, eggs are what hens poop out, they're egg-shaped and made of egg-shell"?

Really not my problem that you don't believe in science.
