Fact-check: “Alien sphere discovery”
Verdict: Unverifiable (10% confidence)
The phrase is too ambiguous to grade as a factual claim. The best-documented candidate — Avi Loeb's team recovering metallic spherules from the Pacific in 2023 — remains scientifically contested: independent analyses found the spherules are likely terrestrial, and no peer-reviewed study confirms extraterrestrial or non-human manufacture. The Buga Sphere (Colombia, 2025) has been assessed by credible scientists as almost certainly human-made.
