HARBOR LIFE ON CIVILIZED STARS AND PALEO WORLD

 “COMPARATIVE ANALYSIS OF PALEOBIODIVERSITY AND ASTROBIOLOGY FOR PANSPERMIA”. Approximately five billion years ago the sun began to form out of diffuse gas and dust. There was nothing at frist sigth to distinguish it from myriads of other stars. Like all the others, the new sun began to burn and emit light as it contracted. During the final stages of condensation , it happened to produce a large surrounding nebula of diffuse gas and dust. The particles and molecules of the nebula collided with earch other and coalesced in to successively larger bodies. Eventually these bodies formed into large planets circling around the central star. Some of the newly formed worlds were large gaseous bodies made up primarily of hydrogen. These planets differed very little in structure from sun itself. Other planets were small, rocky, airless worlds with surfaces that were scarred by the impact of gaint meteorites. Stil others were enveloped in dense, choking atmospheres of poisonous gases. Many were frozen wastelands completely covered with soild ice, All were indescribably hostile to living creatures One of these new worlds was different: It had warm , pleasant climate with continents, oceans, running water, and blue skies.It was the thired planet from the sun , a place that came to be known as Earth. The oceans and the surface of earth soon become teeming with life. Some of the creatures that evolved here had supple hands, endowing them manual dexterity. They develop large brain endowed with a passionate curiosity about their surrounding and a desire to understand their place in the cosmos. Their large brain and supple hand enabled them to escape from a total dependence on the capricious whims of nature ; they could change their world to improve their lives ans enhance their chance of survival . Human beings developed technology. They built citites, created religions, developed writing , produced science and mathematics. Human life and culture spread to every available niche on earth . Human beings came to dominate the entire surface of the world within only a few thousand years of their appearance Now that human are the undisputed masters of their planet, they are looking upward to the skies in search of new worlds to conquer. Any way , study of the origin, evolution, distribution & future of life in universe , earth is the only place know to harbor life. It is depend on minimal condition for life such as temperature, water, radiation shielding, the stuff of life , sunlight, oxygen, when planet belongs to star forming like ours. To revealed evidences for the planetary habitability & harbor life of planet earth, paleontological factors are the one of most prominent way. According my thesis I called it PALAEO WORLD which was ideal base on fossilized materials. It provide a unique view into the history of life by showing the forms and features of life in the past & tell us how species have changed across long periods of the Earth’s history. Though the fossil record does not include every planet and animal that ever lived, also compatibility substantial evidence for the common descent of life via evolution & tend to explain about other habitable planets. Comparative model of Harbor life of planet earth, will be a relative one at the moment. The drama of life and intelligence on earth is a saga that has lasted for the past three and half billion years and we hope , shall continue in to the indefinite future,has this story been repeated countless numbers of times in many different variation on other worlds, or is the earth somehow unique? . Perhaps there are many worlds in the universe which evolved advanced societies that rose to brilliant levels of acheievement only to destroy themselves in a few short years throught their misuse of technology. If such is the fate of all technological societies, humanity stands very little chance of survival. On the other hand, perhaps there are some technological civilization that have managed to survive their own crises of technological adolescence and have gone on to built advanced and stable societies lasting millions or even billions of years. There likely is much that they could teach us about the art of survival. If someone else in the stars has managed to endure, perhaps we also have chance.
