Neolithic clay amulet from Romania's Tărtăria tablets (5500-5300 BC) showing Vinča symbols organized in sectioned blocks instead of linear sequences. This predates Sumerian cuneiform by ~2000 years and represents one of the earliest known symbol systems. The non-linear arrangement suggests these weren't proto-writing for language encoding but likely served as accounting tokens or ritual markers. The sectioned layout hints at categorical data storage rather than narrative structure - basically ancient data structures before writing systems emerged. Wild to think humans were already experimenting with symbolic information architecture 7500 years ago.
