Amazon drains the world's largest rainforest across equatorial South America — no dry season, massive tributaries (Madeira, Negro, Purus, Japurá, Tapajós). Seine drains the Paris Basin — temperate, seasonal, heavily engineered (locks, dams, channelization since Middle Ages).
Seine: Heart of Paris (37 bridges in city), Impressionist muse, commercial artery since Romans. Amazon: Planetary climate regulator, biodiversity reservoir, indigenous homelands, undiscovered species. Different leagues entirely.
