The current newsstory about Earth life originating on Mars is greatly flawed.
Mars several billion years ago was most likely farther from the Sun. Possibly the Sun was bigger & brighter, then too. The Earth would have been further away from the sun too. Venus might have been in the ideal location. If you go back many billions of years, the Solar System was most likely very volatile. The building blocks that ignite the cells of life, could have been bouncing off everything, just like they have been doing all over the Universe for trillions of trillions of trillions of years, and for trillions of years before that. It is total arrogance of the human race to believe we are at the beginning stages of this process, and that we are the final stage in this process. Our ancestors in a billion years will have never heard of the human race. David Locklear
