On January 15, 2009, NASA scientists announced what they believed could be evidence of life on the planet Mars. What they had actually found was methane in the atmosphere, a gas that can be produced by either living organisms or non-living geological processes. The origin of the methane is currently unknown, so speculation that Mars is a “living” planet is somewhat premature.

On his widely popular Cosmos science program in 1980, Carl Sagan described our paltry existence in pathetic terms: "We live on an insignificant planet of a humdrum star, lost in a galaxy, tucked away in some forgotten corner of universe in which there are far more galaxies than people." Several developments since then have altered this perception dramatically.

Creationists have often pointed out that evolution is unscientific because it can never be proved by science to be true. It is not happening at present and without a time machine, they can never be sure that it happened in the past.
