Charlie, if you think that JG Blank's rail gun experiments was anything other than further evidence that abiogenesis could have happened on earth, you need to think again. The combination of comet collisions generating polypeptides from amino acids on the comets, adding to the "soup" generated by lightning strikes on sea water in an atmosphere very different from today's, further enhanced the chances of life forming on the earth. The ocean currents would eventually have brought the various molecules together on catalytic rock surfaces, and that's how the first life could have appeared.
