Are we the aliens? Evidence life on Earth was seeded from space: panspermia, astrobiology, origins.


 


What if life didn’t begin on Earth at all? In this truth-first investigation, we test panspermia against the big mainstream ideas—abiogenesis, hydrothermal vents, the RNA World, iron–sulfur surfaces, and clay-templating—to see which story best fits the receipts. From extremophiles surviving vacuum and radiation to comet-borne amino acids and the Rosetta/67P findings, we follow the data and ask: are we cosmic hitchhikers?


 


We break down:


• Panspermia 101 — lithopanspermia, radiopanspermia, and directed panspermia


• Abiogenesis — Miller–Urey, protocells, and the leap from chemistry to biology


• Hydrothermal vents & alkaline vents — nature’s high-energy chemistry sets


• RNA World — information + catalysis (and why RNA’s fragility is a problem)


• Cambrian Explosion — why complexity seems to “switch on” in the fossil record


• Meteorites & comets — Murchison organics, comet 67P glycine, and delivery systems


• Survival in space — tardigrades, Deinococcus, lichen, and deep-time dormancy


• Where to look next — Europa, Enceladus, Titan, Venus’ clouds, and Ceres’ brines
