Summary: Theory of Panspermia or Extra-terrestrial origin of life on Earth has been advanced as an escape from the original question. However this can’t be correct.
Author: Dr Mahesh C. Jain is a practicing medical doctor and has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. This is the only book which deals with origin of nature and universe from null. Twenty-ninth chapter of the book deals with the subject matter of ‘Origin of Life’.

    • Can Terrestrial Life Have Extraterrestrial OriginSummary: Theory of Panspermia or Extra-terrestrial origin of life on Earth hasbeen advanced as an escape from the original question. However this can’t becorrect.Crick (1973) advanced the idea that life was originally seeded on Earth from space– the idea of Panspermia. The British astronomer Fred Hoyle and SrilankanChandra Wickramsinghe have further raised the possibility of Panspermia (1981).The whole idea of Panspermia is the outcome of inability to satisfactorily explainorigin of life on Earth despite accumulation of vast amount of data sinceAlexander Oparin (1924) first published his paper on this subject. He speculatedthat early Earth had reducing atmosphere. He considered it essential for Origin oflife on Earth.Even demonstration of origin of amino acids under physico-chemical influences byMiller – Urey (1953) has not resolved the question of spontaneous origin of life onEarth. In fact much work has been done after Miller – Urey to bridge the gapbetween inanimate and animate but still spontaneous transformation ofinanimate into animate remains a matter of faith and belief. Till date, it is notpossible to even conjecture spontaneous origin of a single polypeptide chain,what to talk about spontaneous origin of the simplest biological cell.The gap between inanimate and animate remains as wide as ever.Demonstration of amino acids, purine and pyrimidine bases in meteoritesbombarded on earth, specifically Murchison meteorite; and presence of polycyclicaromatic hydrocarbons in space does not tell us anything about origin of life,whether on Earth or elsewhere. These findings only indicate feasibility ofspontaneous origin of these chemicals under physico-chemical influences andnothing more.All the work done so far demonstrates only one or more aspect of ‘life likeactivity’ but does not explain origin of life itself. Known properties of RNA are far
    • from constituting life. Even recent analytical study by Bokov and Steinberg (2009)indicating feasibility of step-by-step evolution of ribosome at structural levelbeginning from a small core leaves much to be desired to constitute life.Theory of extraterrestrial origin of terrestrial life, i.e. Theory of Panspermia mayprovide some relief from the question of explaining origin of life on Earth but itlands us into the question of explaining origin of life in extra-terrestrial space. So,we aren’t in any better position with our original question.Theory of extraterrestrial origin of life leads to further questions. If life wasseeded from space, than how could it be found 5 Km below the surface of Earth inthe form of extremophiles bacteria or 9000 meters below sea level on the oceanfloor of Galapagos rift in the form of Poganophora. Barophillic Marine microbeshave been found at more than 10 Km depth in Marianas Trench. Therefore,distribution of life on Earth is inconsistent with extraterrestrial origin of life.Theory of Panspermia also raises the question of adaptation or survival of alienlife under the conditions seen on Earth. All the available evidence indicates thatalien life if any, must have originated under quite different environmentalconditions than seen on Earth. So, how could alien life survive on Earth and evolveto the present state? Gradual adaptation over an immense period of time in linewith Darwinism is more easily said than can be done.Hence, Theory of Panspermia or Extraterrestrial Origin of life is nothing butscientific fiction created with the sole purpose, to divert attention from thequestion of origin of life. Author: Dr Mahesh C. Jain is a practicing medical doctor and has written thebook “Encounter of Science with Philosophy – A synthetic view”. The book beginswith first chapter devoted to scientifically valid concept of God and then explainscosmic phenomena right from origin of nature and universe up to origin of lifeand evolution of man. The book includes several chapters devoted to auxiliaryconcepts and social sciences as corollaries to the concept of God. This is the onlybook which deals with origin of nature and universe from null. Twenty-ninthchapter of the book deals with the subject matter of ‘Origin of Life’.
