I have found myself really looking forward to these video's and it's not just because the music in the background is so amazing. Great work. If life on Earth was seeded by extremophiles from Mars via a meteorite, how would that happen? Would the meteorite have literally bounced off of mars as in your video? How does a large piece of rock get from Mars to Earth? I realize that this is just a hypothesis, but how do people explain that?
Mars rocks hit Earth with surprising frequency, even today. You could say that the inner solar system "geologically communicates". Remember Mars does not have a very strong magnetic field so it gets hit by meteorites all the time (of various sizes) and Martian dust and rocks gets jettisoned up into the weak atmosphere and into the solar system. Sometimes the debris finds its way to Earth! We know that this would have happened at a much higher frequency in the early solar system because the early solar system was so chaotic and meteorites collided with planets at a very high frequency. We also know that simple prokaryotes can exist almost anywhere... even on meteorites and asteroids. Of course we don't know whether abiogenesis first started on Mars and then early life was transferred to Earth. It is still just a hypothesis and not necessarily more likely than the alternatives that abiogenesis just started on Earth, or abiogenesis started on both Mars and Earth simultaneously!If life on Earth was seeded by extremophiles from Mars via a meteorite, how would that happen?
