Your father heard it first, on a ham radio in his shed. Now an archaeologist in Cairo is hearing it too, from the oldest monuments on Earth. One voice on channel 7. Visited, or human-made? You decide.
Your scanner has two lenses. Believer shows the ancient-astronaut reading. Sceptic shows what archaeologists found. Ruth will be on the radio.
File your verdict from what you scanned. Both answers count, and Ruth will hear about it.
Göbekli Tepe, Nazca, Abydos, Palenque and Sumer follow in later parts. Your notebook and verdicts are saved in this browser.
