How life originated on earth is a question that people have wondered for ages. One possibility that answer this brilliant question is the panspermia theory, which suggests that life on earth originated thanks to the contribution of cosmic beings that come from any point in the universe. This hypothesis does not speak of organisms ranging in meteorites moving through the universe to the Earth to conquer it, but it speaks of complex chemical substances which had been formed earlier from the origins of the universe, which reached the earth at any given time.
This hypothesis emerged when scientists found organic molecules in meteorites from the universe. Some investigators wondered if the abiotic production of organic materials in the soil was absolutely basic to the origin of life. Maybe some organic materials from elsewhere in the universe had arrived in the early earth.
Statistics have showed 7.5% of rocks from Mars reached Earth. These rocks would travel between less than 100 years to 16,000 years and more to get to Earth. Some proponents include Gyon de Montlivant, who proposed that life came from moon, H.E. Richter, who suggested life came from meteorites or comets, but Svante Arrhenius proposed this theory.
While this idea may seem straight out of a science fiction movie, some evidence suggests that an extraterrestrial origin of life may not be such impossible idea.
One argument that supports the panspermia theory is the emergence of life soon after the heavy bombardment period of earth, between 4 and 3.8 billion years ago. During this period, researchers believe the Earth endured an extended and very powerful series of meteor showers. However, the earliest evidence for life on Earth suggests it was present some 3.83 billi...

...at different points in the past, this observation presents an interesting argument for panspermia. While this study does not provide conclusive evidence for presence of life in outer space, it does raise the possibility that our galaxy may be fool with bacterial spores.
An important thing to note about the panspermia hypothesis is that it gives no explanation for how life that arrived on Earth came to be. Even if we are able to show that life on Earth was a result of panspermia, the question of where and how life originated will be a lot harder to answer. So far our knowledge of the solar system suggests that life is unique to Earth, but, as science and technology advance, we will have to modify ideas that we currently see as facts. It remains to be seen if the questions about the origin of life on Earth and the origin of life in the universe have the same answer.
The disaster theory, Gould claims, is an example of good science. It has testable evidence and has an impact on studies in other fields of science, it develops further and explains why the extinction of dinosaurs occurred simultaneously with other events. This theory suggests that a large comet hit the Earth sixty five million years ago, causing the cloud of dust to rise into the sky and to block sunlight. As a result, world temperatures went down significantly, the ice age bega...
The primordial Soup theory was discovered in 1920. According to the Russian scientist A.I. Oparin and English Geneticist J.B.S. Haldane life started in a warm pond/ocean in a process that took place 3.8 billion years ago. A combination of chemicals made fatty acids which made protein. In this process a molecule was born in the atmosphere. The molecule was energized with lightning and rain making “organic soup”. The first organisms would have to be simple heterotrophs in order to survive.
The next theory that he disproved was the “Primordial Soup Theory”. Sir Fred Hoyle scoffed at the ridiculous atheistic notion when he said, “The notion that a living cell could be arrived at by chance in a primordial organic soup here on earth is evidently nonsense of a high order.” “There was no primeval soup, neither on this planet, nor on any other, and if the beginning of life were not random, life must therefore have been the product of purposeful intelligence” (Donyes
(bethinking.org) Life demands a certain chemistry. The information that makes up any living being is stored on a long molecule called DNA. (answeringenesis.org) If the laws of chemistry were different life as we know it would not be possible. The question of how the universe came to be as it is and how we as humans came about often resonates deeply, particularly with scientists. Many conversations between scientist Christians and other scientists about God and Christ end up considering biological evolution or the Big Bang. Chemistry’s contribution to the story of our origins the transformation of inanimate matter into the first living organisms is much less well understood than other areas of our origins. However, many parts of the process are increasingly understood and we may eventually know the molecular details of the origin of life. As Christians, we need to think through how we would respond to a developed theory in this area.
The Precambrian Era is when the Earth formed. Earth was barley a spec of dust in outer space and as time went by it gathered ice, rock and more dust particles. It eventually formed into a big rock flying around in space. The Earth was extremely hot and so when it rained the rain would evaporate in mid air or immediately after it hit the ground. But even though it evaporated these great rains cooled the Earth eventually building up water in lower areas creating oceans. The Earths atmosphere was water vapor, carbon dioxide, nitrogen and gases. After awhile oxygen level grew in the atmosphere. The earliest life forms were single celled organisms that lived in the oceans. These organisms used light energy to produce food called photosynthesis. These were called Prokaryotes and Eukaryotes. The evolution of multi celled organisms were Dramatic in change.

The existence of life – Aliens, beyond our planet has been a controversial topic for several centuries, and is a debatable issue even today in the 21st century. What is our topic you may ask? Aliens, Do, Exist. According to theoretical physicist, Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This is a bold claim, but there is evidence to support this statement. The evidence we seek is in the many Alien occurrences we have experienced throughout human history.
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
Life may had existed on Mars because it was a habitable world. In 2004, this discovery was made NASA's Opportunity rover at Eagle Crater that Mars had water. At the Martian surface there was liquid water, and if there was water that means that living organisms like bacteria, may have existed on Mars. Many scientists believe water did existed on the planet because three NASA rovers found rocks with appearance of channels, streams and even oceans spotted by orbiting satellites. A question was brought up to Richard Quinn, a SETI Institute researcher with Ames' Planetary Systems Branch, if Mars was a habitable environment? "Based on what we know about life in extreme environments, interpretations of mission results indicate that we are currently exploring habitable ancient environments on Mars, and I believe that these are solid interpretation...The question is about preservation potential of bio signature rather than intrinsic habitability of the ancient environment." (Quinn, The Daily Galaxy)
The origin of life was created by our God. In the beginning God created the heavens and the earth. (Genesis 1:1 New American Standard Bible). It’s understood in Genesis 2:7 (New American Standard Bible) that life in fact was created by God. God created man from dust on the ground, breathed it, and man became a living creature. God created humans to be able to reproduce to create more life. God created many
“The greatest mystery of existence is existence itself” (Chopra). Chopra, a world-renowned author, perceives the existence of life as a truly mystifying cerebration. The pending question that many scientist, and even theists, attempt to answer is how life ultimately began. Currently, the mystery is left with two propositions, evolution and creation. While both approaches attempt to answer the origins of life, evolution and creation are two contrasting concepts. Evolution views life to be a process by which organisms diversified from earlier forms whereas creation illustrates that life was created by a supernatural being. Creation and evolution both agree on the existence of microevolution and the resemblance of apes and humans but vary in terms of interpreting the origins of the life through a historical standpoint. A concept known as Faith Vs Fact comprehensively summarizes the tone of this debate, which leads the question of how life began.
Pan (Faunus) was the god of fertility, and the special patron of shepherds and huntsmen; he was chief of the Satyrs, and head of all rural divinities.
Mankind’s origin was not a result a ridiculous theory that a big bang occurred, causing life to begin. Neither was mankind a single cell organism floating around in the ocean. Mankind was not formed by a mutation of organisms in the sea. Man’s origin did not come from another life source from another planet.
The question of whether there is other intelligent life form beside humanity has been in great academic discourse for much of the last century. Many conspiracies about intelligent life forms have emerged and inspired many great works of art in various genres. Although definitive proof of their existence has yet to be found, the search for intelligent extraterrestrials have lead innovations to new heights in space explorations. This research will attempt to show with good reasons that it is unlikely for intelligent extraterrestrials to exist, but the possibility of microorganisms to live beyond our solar system is plausible. Schick and Vaugh define “extraterrestrial” as an intelligent being foreign to earth.
• Geologists have discovered meteorites on the earth that have existed for many thousands of millions of years, way before the earth came into existence.
