I would love it if it was determined that life had (or does) exist on Mars. I would really like to know before I die, and I don't think I have all that many years left. You science guys better get on the stick here.

Of course, as LH mentioned, 'life' can and maybe does means lots of things. For all I know there are forms of life in 'dead' things--steel, salt, atoms. I really don't know how people go about defining what life is or how one can determine if something meets that definition. It was pretty cut and dried when I was in Grade 9 Biology. I think then that 'life' had to meet ten criteria. But that seems to change with time. I suppose that if we met other intelligent life one of the difficulties would be communication.
