I haven't read the word "panspermia" here yet. The idea that life here started on another planet and somehow landed on this earth through comets or alien garbage dumps. Like we are doing now on Mars. If Sharon's and Gordon's theory holds true this is the most viable option.

I end the article suggesting the possibility of panspermia (even indicating that I favour it):

    That is not to say that life could not have originated completely or partially from space. The idea that asteroids with complex organic compounds seeded our planet during the late-heavy bombardment 4 billion years ago is quite possible. But positing the chemical compounds necessary for life existed 9.7 billion years ago requires more evidence than a logarithmic scale with cherry picked data points.
