Life -Sustaining Planets

Abiogenesis is the natural process of life arising from non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but a gradual process of increasing complexity. Life on Earth first appeared as early as 4. 28 billion years ago, soon after ocean formation 4. 41 billion years ago, and not long after the formation of the Earth 4. 54 billion years ago. The earliest known life forms are microfossils of bacteria. Researchers generally think that current life on Earth descends from an RNA world, although RNA-based life may not have been the first life to have existed. The classic 1952 Miller–Urey experiment and similar research demonstrated that most amino acids, the chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. Complex organic molecules occur in the Solar System and in interstellar space, and these molecules may have provided starting material for the development of life on Earth.



"We are just beginning to try and figure out quantitatively how all this might smooth a surface," Dr. Thomas said in the May 17, 2013 New Scientist. Moons, Myths, Etc. Our bewitching, and sometimes bewildering Moon, has long been the inspiration for magical myths, weird legends, bedtime stories, and beautiful poetry. Earth's Moon is a very ancient symbol of femininity, as well as for wild bouts of strange madness and romantic love. Some ancient, traditional legends and childhood stories tell of a man's face etched out on its shining surface, while others tell strange tales of a "Moon Rabbit." Lovely, ancient myths, tales, and bedtime stories aside, Earth's Moon is a very real object. It has been a companion-world to our Earth almost from that very ancient era, when our Solar System was first forming, about 4.5 billion years ago. Soul Mates and the Moon. When we think about finding a soul mate, we think of someone who "gets us" on a profound emotional level-someone with whom we can share our darkest secrets, our hopes and dreams. Like a mother goddess, our soul mate accepts us unconditionally. He or she nurtures and loves us no matter what happens. In other words, when we dream of finding a soul mate, we are tuning in to the energy of the Moon!
