You're a true skeptic. I don't blame you, thousands of others are skeptical. That still doesn't explain how these artifacts were created. You''re welcome to try replicating them, if successful you will be famous around the world. There are curators around the world hiding discovered items and not allowing the public to see them, because they run counter to existing prevailing theories. I'm skeptical of so-called experts because they won't openly display these strange items that run counter to what they believe. If super-dooper tools (your description) exist, they may be hidden or may have been destroyed by curators because they don't fit the narrative. Don't be a flat-earther and accept just one narrative because we don't always know what we don't know.
with ancient tools perhaps. Just because we don't know how THEY did it without our tools does not mean we can't do it with our tools. It also does not mean we couldn't make them without our tools either.
I still haven't been directed to anything we can't make that they did. Everything I've seen on those web sites could be made now.
