@Kolyo,
Good question, So What?
Well it seems to stem from a reaction to this post that I made, but the reaction seems irrational.
If you forget the past, and simply look to the future, you can easily see the day when humanity will take life to another planet or moon nearby. Now this life will not include cattle and corn that we could use for food, as there is no air of soil. What we will be trying to introduce, would be simple photosynthetic plants such as planktons that would create both sugar and Oxygen from sunlight, just as the Mars rover creates electricity from sunlight. So these life forms being simple, would still undergo evolution and would in your opinions obviously become more complex. If you say that there is no evidence of this you would be correct, but the evidence of this is equal to evolution springing from a warm pond.....However, leaving the Earth is a must do for humanity to continue existing after a point, thus it will be achieved, given time.
Based on that someone made an inference of air and soil, or it might be from another forum. Mee dunnos
