Correction (6/17/08): This article originally stated incorrectly that isotopes are named for the number of neutrons in their nuclei, instead of the total number of protons and neutrons.

   ".. carbon 12, named for the number of neutrons in its atomic nucleus."
   In the best interests of Science, science journalism and public information,, please correct this error as soon as possible.

   Fascinating. A meteor crashed to earth and life began as a result. Interesting synopsis.

   Meteorites contain organic compounds and water. Based on this strong evidence several decades ago, some scientists had conjectured that terrestrial life might have originated from space.
   There are also scientists who believe that it is highly probable that life began on earth billions of years ago after researchers successfully produced rudiments of amino acid in the lab. Yet others have been more skeptical, arguing that the probability of life formation from there on was simply too minute to be plausible.
   Is there a necessity to continue searching feverishly for ET? Perhaps not, we could have been the ET ourselves, we are the ET (take it or leave it).

   Life Defined:
   
   Scientifically, not technically
   
   Tomorrow's comprehension of life and its evolution
   
   Intriguing Darwinian implications
   
   Intriguing technological developments potential
   
   Look at these life definitions, reflect about their implications...
   
   -----------------------------------
   
   Comprehensive Definitions Of Earth Life, Earth Organism, Gene, Genome And Cellular Organisms.
   
   Earth Life: 1. a format of temporarily constrained energy, retained in temporary constrained genetic energy packages in forms of genes, genomes and organisms 2. a real virtual affair that pops in and out of existence in its matrix, which is the energy constrained in Earth's biosphere.
   
   Earth organism: a temporary self-replicable constrained-energy genetic system that supports and maintains Earth's biosphere by maintenance of genes.
   
   Gene: a primal Earth's organism.
   
   Genome: a multigenes organism consisting of a cooperative commune of its member genes.
   
   Cellular organisms: mono- or multi-celled earth organisms.
   
   -------------------------------------------------
   
   Nature, Origin And Function Of Earth Life
   
   
   Nature of Earth life: a replicating construction temporarily constraining and maintaining energy.
   
   Origin of Earth life: serendipitous energy-induced formation of Earth's primal organisms, individual independent genes.
   
   Nature of Earth's organisms: temporary self-replicable constrained-energy genetic systems that support and maintain Earth's biosphere by maintenance of genes.
   
   Function of Earth life: uphold and maintain as much constrained energy as possible by upholding and maintaining Earth's biosphere.

   Earth Life
   In plain English, not in academEnglish verbiage.
   
   - Earth life is just another naturally selected mass format.
   - The primal base organisms of Earth life are the genes, i.e. the RNA nucleotides.
   - All Earth life formats are progenies of genes evolution.
   - Genomes are organisms evolved, and continuously modified, by the genes as their functional templates.
   - Genetics is a progeny of culture, which is reaction to circumstances.
   - The drive and goal of evolution of ALL mass formats is to enhance their energy constraint, to postpone their reconversion to energy, which goes on at constant rate since the Big Bang.
