Immediate to Short-Term (Days to Centuries)

• Hours to weeks: Power grids fail; nuclear reactors melt down without maintenance[11].
• Months to decades: Urban areas flood as drainage systems fail; buildings decay from weather and plant growth[6][11].
• 100–300 years: Steel structures collapse; concrete buildings crumble[5][7]. Most cities become overgrown forests[6].

Medium-Term (Thousands of Years)

• 1,000 years: Visible surface structures (e.g., roads, monuments) are buried or eroded. Plastics fragment but persist chemically[5][7].
• 10,000–250,000 years: Nuclear isotopes (e.g., plutonium-239) remain detectable in sediments and ice cores[7]. Mining tunnels fill with sediment but leave identifiable "industrial fossils"[7].
• 500,000 years: Microplastics and polymer layers in ocean sediments endure[5][10].

Long-Term (Millions of Years)

• 1–7 million years: Fossils of humans and domesticated animals persist. Geological strata show elevated carbon levels and mass extinction markers[4][8]. Deep mines and landfills remain as distinct layers[7][10].
• 50–100 million years: Continental drift subducts surface evidence; satellites decay or drift into space[3][10]. Only deep geological traces (e.g., mine shafts, isotope ratios) might endure[3][10].
• 250 million years: Next predicted mass extinction eradicates all mammals, including any remaining human traces[9].

Near-Permanent Traces

• Space artifacts: Lunar landers, Mars rovers, and Voyager probes persist for billions of years[3][10].
• Radio signals: Human broadcasts travel through space indefinitely at light speed[5].

Key Factors

• Detection likelihood: Aliens or future species could find traces for 100+ million years via deep geological analysis or space exploration[5][10].
• Total erasure: Requires Earth's destruction (e.g., solar expansion in 5 billion years)[10].

We do have an impact but the earth will 100% be ok when we are dead and gone eventually. A million years ain't shit to the earth.

We humans are a virus…a parasite and the earth will be better off once we are extinct.
