The observation is that of all life forms that have ever existed upon earth, four fifths of them are debatable. Which means, there is no clear unadulterated fossil evidence of their having been here. There is no dinosaur bone. Rather the existence of fourth fifths of past life on earth is assumed from scanty physical evidence from peculiar, yet familiar structures, which support a theoretical over view of what it is past living things did, or might have done, had they been here. As an example, the argument is, our planets breathable oxygen is a product of ancient life forms, a pollution which some of us learned to cherish as we fed upon creatures that produced breathable oxygen as an unwanted byproduct of their own life cycle. A perspective is to think of the past five thousand years of our history and say that of those five thousand years of history there is no real concrete evidence of anything ever happening prior to 1000AD. In the context of United States history, a history which begins around the war of independence, it would be as though records began in something like 1960. All of which is grist to a creationist mill.
For the more modern people still aboard it, the planet Earth is about four and a
half billion years old. Which makes Earth about one third the age of the
Universe. From a great many sources of evidence the estimate is that a little
over three and a half billion years ago the first life forms emerged upon earth.
On April 22nd of this year, which is about two weeks ago, a Netherlands based
group called Mars One asked for a million 'psychologically stable' volunteers
who are 'proficient in the English language' to support their vision of
colonizing Mars sometime in 2013, which they claim is an imperative if we are to
'understand our place in the universe.' Since April 22nd there have been
78,000 volunteers. My question is "why is their answer on Mars?" And
while I suspect the Mars One answer is somewhere in the word "mission,"
it's interesting that Mars One is planning to fund their search for an
'understanding of our place in the universe' with reality television
programming. Nor does a person have to lie about his age on the
application because so long as you are over eighteen and can mutter in something
like English or plan to be able to soon, there is no upper age limit.
