Essay on How Did Life on Earth Begin

Life, it might be argued, is the distinguishing feature of all organisms and may most usefully be thought of as involving various kinds of complex systems of organization providing individual organisms with the ability to make use of those energy sources available to them for both self maintenance and reproduction. Underlying this deceptively persuasive definition, however, lie those persistent traditional problems inherent in the search for an essential, distinctive substance characteristic of all forms of life. Additionally, as evolution theory makes clear, there is the problem of borderline instances, organisms of which it is not easy to say whether or not they may be defined as being alive. One such case

Stanley Miller started the idea that life could have started when carbon and other ingredients combined. He assembled a contraption made out of flasks and tombs in the lab. He fill one flask with gases to represent Earth's primitive atmosphere and connected that to another flask with water to represent the ocean. He put an electric charge through that.simulated lightning going through early atmosphere. After a couple of day, all this brown goo all over the reaction vessel. He said, now he had amino acids in the vessel. Amino acids are compounds that are form when carbon and other elements linked together. They are building block of protiens and cell, which were vital ingredients of all living things. His experiment showed that life can be formed in the harsh condition of early earth.

Chemical evolution is the main exploratory clarification for the birthplace of life. Like every scientific theory, the hypothesis of chemical evolution has an example part that makes a case about the common world and a procedure segment that clarifies that patter. The example part is that notwithstanding little atoms, complex carbon-containing substances exist and are needed forever. The procedure part is that in Earths early history, straightforward concoction mixes consolidated to frame more mind boggling carbon-containing substances before the advancement of life. The hypothesis keeps up that inputs of vitality prompted the development of progressively complex carbon-containing substances, coming full circle in an intensify that could recreate

Defining living organisms from nonliving materials can be difficult given the multitude of characteristics defining each. Biologists have identified at least six key properties that appear to be shared by most, or all, living organisms on Earth, according to the 3rd edition of Life in the Universe by Jeffrey Bennett and Seth Shostak. The general properties defining life on Earth are: order, reproduction, growth and development, energy utilization,

al 2014) citing that the Miller-Urey experiment only provides one possible mechanism for their abiotic synthesis, and does not explain the origin of life. It has since been discovered, that the earth’s early atmosphere is nothing like what Urey and Miller recreated in the flask with scientists believing that the Earth had a very neutral atmosphere, similar to the current atmospheres of mars and Venus comprising mostly of carbon dioxide with small amounts of hydrogen and nitrogen. This led to the proposal of new theories such as (Mulkidjanian Galperin 2009) theory suggesting that life on Earth originated at photosynthetically-active porous structures, similar to deep-sea hydrothermal vents, made of zinc sulfide. They stipulate that under the high pressure of a carbon dioxide dominated atmosphere, these zinc suffice structures could form on the surface of the

Oparina/Miller hypothesis theorized was because of absence of free oxygen, chemicals, and so on could shape inorganic mixes for emerged on this planet.

Half a century ago, President John F. Kennedy gave a speech about the importance of government always maintaining an attitude of neutrality towards religion. President Kennedy stated, “I believe in an America where the separation of church and state is absolute.” The United States has been a country, in which the separation of church and state has been adopted and assumed to be practiced, but there has been a perennial conflict disrupting the balance between church and state. In his innovative film, The Revisionaries, director Scott Thurman exposes how the public education system has become the latest battleground in the face of an old conflict – between religion and science – challenging the ideological edifice on which the nation stands.

Although early Earth was hostile, it provided a great environment for the production of organic molecules. Events such as lightning, volcanic eruptions, meteorites, radioactivity in the Earth’s crust, and the easy access of ultraviolet light, are thought to have provided the energy for these molecules to produce. Therefore, the conditions of early Earth were critical in the commencing of the first organic molecules.

In the old Earth view of the original creation of Earth we are told about the

Thought the history and as Science has developed exponentially, we the human beings have found answers through the scientific perspective to most of our reality. Although there are still, many things to be discovered and proved. One of this and most important the explanation here in this letter, is the conception of life in our planet. We can go back to any time in

Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started.

Creationism is a religious metaphysical theory about the origin of the universe. It is not a scientific theory. Technically, creationism is not necessarily connected to any particular religion. It simply requires a belief in a Creator. Millions of Christians and non-Christians believe there is a Creator of the universe and that scientific theories such as the the theory of evolution do not conflict with belief in a Creator. However, fundamentalist Christians such as Ronald Reagan and Jerry Falwell, have co-opted the term 'creationism' and it is now difficult to refer to creationism without being understood as referring to fundamentalist Christians who (a) take the stories in Genesis as accurate accounts of the origin of the universe and

One of the most revered investigations of Abiogenesis (life arising from non-living matter) is the Miller-Urey experiment conducted in 1952. This experiment (as depicted) involved the simulation of primordial conditions on Earth and testing whether “natural stimulation” such as lighting and heat could have resulted in the synthesis of simple organic compounds. Several compounds thought to have been abundant in the atmosphere 3.8

According to astronomical research and geological evidence, scientist indicate the universe is approximately thirteen thousand eight hundred and twenty billion years old. The first link to humanity started with a primate group called Ardipithecus. While our ancestors have been around for about six million years, the modern form of humans only evolved about two hundred thousand years ago. The age of the Earth is estimated about four point fifty four billion years because that is the age of the oldest rocks with fossil evidence of life on earth. The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are four point three billion years old. The study of the origin of life on Earth, more specifically abiogenesis, is the natural process of life arising from non-living matter. Life on Earth is believed to have began from organic compounds about three point eight to four billion years ago. Despite several competing theories for how life arose on Earth scientist only know when life first appeared on Earth and are still far from answering how it appeared. Since it is hard to prove or disprove them, no fully accepted theories of the origin of life exists.

. The Miller-Urey experiment (or Urey-Miller experiment) was an experiment that simulated hypothetical conditions present on the early Earth and tested for the occurrence of chemical evolution (the Oparin and Haldane hypothesis stated
