Taphonomic bias and environmental factors dictate what survives. Acidic, moist soils rapidly destroy organic material, while dry alkaline deserts preserve it longer. Future archaeologists may only find isolated artifacts in deserts, missing submerged or eroded cities. Chemical signatures (iron oxides, synthetic polymers) may be the only trace of past civilizations.
Acidic, moist soils destroy organics quickly, while dry alkaline deserts preserve them; future archaeologists may only see desert artifacts, missing drowned cities. Synthetic polymers could be the sole chemical clues.
