I actually fact checked this and it’s true.

    Eh I doubt it. Every single nuke ever built combined still doesn’t come close to the power of the Chicxulub asteroid (the one that killed the dinosaurs) and even that impact didn’t come close to eliminating all life on Earth. Unless someone accidentally compresses a mountain into an artifical black hole or something there probably is no way to wipe out all life on Earth.

      Mars was once habitable but lost it’s magnetic field, wiping it’s atmosphere. Venus was once habitable but taken over by a runaway greenhouse effect.

      I’m not saying they ever had life or that we’re going to suffer the same fate, but it’s definitely possible to wipe a planet clean.

        75% of all species, not all life. Larger species and photosynthesizers were more heavily affected, while smaller species, scavengers, and deep sea life were less affected.

        And I’m not a biologist, but I’m pretty sure even 75% of all life, not species, still wouldn’t be close to completely ending life on Earth, cause in the end as long as some microbes survived around a hydrothermal vent somewhere total extinction would be avoided.
