  8.  @garethdean6382  I thought the concept was dubious when I first heard of it early '90's. Since having learned how common, over millions of yr.s, stuff get's blasted off planets and moons from impacts above escape velocity and land on Earth and every other body, with only surface cooking, many microbes could survive the interior of a small meteor frag., high G's means nothing to them. They are fairly cool by the time they hit the ground interior doesn't get hot necessarily, at least hitting Earth we know and we can simulate the rest. We can resurrect multi million yr. old 'dead' organisms dug deep out of Earth (so I'm told). Certainly 40k yr. frozen bacteria come back to live when thawed. We retrieved a camera left on our moon for several months, some insulation in the cam was infested with happy bacteria....from Earth but a surprise. Bacteria thriving in boiling hot springs, on the surface of the space station (reportedly from contact with near zero atmosphere!) Thriving in nuclear reactors, 2 miles below our feet in solid rock with extremely low metabolism....on and on and on.... It's easier for me to comprehend that then abiogenesis happening as fast as it needed to on Earth...NOT ruling that out but the stage could be astronomic instead of just Earth. I can connect the dots on inter stellar panspermia likelihood, previously I'd only said within the solar system. Now I realize star systems even get ejected from their galaxy, shotgunned across the local cosmos if they can take their planets with them they will deliver life to neighboring galaxies occasionally! (yes that could take billions of yr.s, wild idea but I believe in the persistece of MICROBIAL life to that degree, I'd bet big bucks we find microbes on half a dozen Sat./Jupiter moons and Mars and I'd bet a little that it's related to Earth life) Pardon my rant! :D
