Panspermia?

What did scientists find? Bacteria or DNA in meteorites? Does this necessarily mean that life came from another planet?

    Panspermia is merely a hypothesis and not a very good one. No, scientists have not found any (non-earth) dna, bacteria or any other suggestion of life in meteorites. The whole idea of panspermia simply moves the creation of life from earth and places it somewhere else. But again, there is no evidence for it. Building blocks of life, amino acids, are found in the spectrograms of some comets and in interstellar nebulas. The miller-urey experiments in the late 1950s and early 1960s showed that amino acids can form very easily.

    Amino acids are not life.

    Life on Earth may have come from another planet, but where did that life on the other planet come from? Scientists found bacteria in meteorites, and the bacteria had DNA in them, so the scientists found DNA, too. Humans came from Mars.

    Scientists did not find anything. There are organic molecules in space. There are many more organic molecules on Earth.

    From there to a conclusion that life came from space requires a very special ingredient: religious faith.

    Which is pretty much why nobody with any knowledge takes this thing for real.

    I believe the jury is still out on that one. They've found impressions that MIGHT be bacteria or viruses, but they aren't definitive. They could also be just imperfections in the rocks, if I remember right.
