Theories on the Origin of Life
Origins Of Life
The origin of life on Earth is a scientific problem which is not yet solved. There are plenty of ideas, but few clear facts. It is generally agreed that all life today evolved by common descent from a single primitive lifeform. It is not known how this early form came about, but scientists think it was a natural process which took place perhaps 3,900 million years ago. This is in accord with the philosophy of naturalism: only natural causes are admitted.
It is not known whether metabolism or genetics came first. The main hypothesis which supports genetics first is the RNA world hypothesis, and the one which supports metabolism first is the protein world hypothesis. Another big problem is how cells develop. All existing forms of life are built out of cells
The origin of life is one of the great mysteries in the Universe. To determine the origin of life, scientists are investigating the problem in several different ways. Some scientists are studying life on our own planet. Some scientists are seeking out life or fossil life on other planets or moons in our solar system.
And other scientists are trying to detect life in other solar systems, either by measuring life's effects on the atmospheres of distant planets or by measuring artificial radiation like radio signals that may be produced by advanced life.
Thus far, the most fruitful approach has been to examine life on our own planet. However, even in our own backyard, it is difficult to determine life's origins because it began at least 3.5 billion years ago. We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth..
Rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones. Nonetheless, 3.5 billion year old rocks with fossils can be found in Africa and Australia. They are usually a mix of solidified volcanic lavas and sedimentary cherts. The fossils occur in sedimentary cherts..
7 Theories on the Origin of Life
It started with an electric spark Lightning may have provided the spark needed for life to begin. Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days.
Over millions of years, larger and more complex molecules could form Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well.
Molecules of life met on clay
The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now.
The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.
How the Moon Works
From anyplace on Earth, the clearest thing in the night sky is usually the moon, Earth's only natural satellite and the nearest celestial object (240,250 miles or 384,400 km away). Ancient cultures revered the moon. It represented gods and goddesses in various mythologies -- the ancient Greeks called it "Artemis" and "Selene," while the Romans referred to it as "Luna."
Because the moon is so close to the Earth relative to other celestial objects, it's the only one to which humans have traveled and set foot upon. In the 1960s, the United States and Russia were involved in a massive "space race" to land men on the moon. Both countries sent unmanned probes to orbit the moon, photograph it and land on the surface. In July 1969, American astronauts Neil Armstrong and Edwin "Buzz" Aldrin became the first humans to walk on the moon. .
During six lunar landing missions from 1969 to 1972, a total of 12 American astronauts explored the lunar surface. They made observations, took photographs, set up scientific instruments and brought back 842 pounds (382 kilograms) of moon rocks and dust samples. What did we learn about the moon from these historic journeys?.
Constantly reminds you of love that round softness blue colour of ocean, Picture the world she is older now much older than she ever thought she will get, She looks at herself as she spins Arms loaded with the trophies of her most successful child The pylons and mines The powerplants shimmer in her still, cool breath Now, is that a smile that plays across her lips Or is it a tremor of dread? The sadness of mothers as they watch the fates of their children unfold

WHAT DO WE KNOW AND WHAT WE DO NOT KNOW
Could aliens have found humans first without us realizing? Scientists claim intelligent beings could be quietly watching humankind in a 'galactic ZOO' to protect us from the distressing truth of their existence
We may not yet have found evidence of alien life, but that doesn’t mean it hasn't found us.
This is according to a group of scientists who gathered this week in Paris to discuss why, despite decades of searching and the high probability that life exists beyond our own atmosphere, we’ve yet to make contact.
One possibility, albeit unflattering, could be that intelligent aliens are intentionally shielding us from the truth because humans would struggle to cope with the reality of their existence, some say.
GOD or GODS
Do We Need One God or More And Why?
God or Gods
In monotheistic thought, God is conceived of as the supreme being, creator deity, and principal object of faith.The conceptions of God, as described by theologians,[who?] commonly include the attributes of omniscience (all-knowing), omnipotence (all-powerful), omnipresence (all-present), and as having an eternal and necessary existence.
Depending on one's kind of theism, these attributes are used either in way of analogy, or in a literal sense as distinct properties. God is most often held to be incorporeal (immaterial). Incorporeality and corporeality of God are related to conceptions of transcendence (being outside nature) and immanence (being in nature) of God, with positions of synthesis such as the "immanent transcendence".
On December 15, 2015, Wheaton College, a flagship of evangelical educational institutions, placed one of its professors on administrative leave for “theological statements that seemed inconsistent with [their] doctrinal convictions.” Five days prior, donning a hijab and staking her position on a variety of controversial matters,
Larycia Hawkins had stated on Facebook, “I stand in religious solidarity with Muslims because they, like me, a Christian, are people of the book. And as Pope Francis stated last week, we worship the same God.”
Angels and Demons
While the description of demons may sound scary, remember they are defeated enemies of God. They have no competition against Him and His army of angels. God’s love conquered sin and death, triumphing over Satan and all his empty promises.
We have been protected from the “evil one” and the many demons who are active in the world. Continue to spend time with the Lord, and give Him your full attention. You won’t have to worry beyond that.
Christianity is one of the three major monotheistic world religions. Like Jews and Muslims, Christians believe one God who created the world and takes an interest in the humans who inhabit it.
This article explores what Christians believe about the characteristics and nature of God. The major theological belief that Jews and Muslims do not share - the doctrine of the Trinity - is explored in a separate article.
