Did life on Earth come from comets?

Question

Not too long ago, scientists believed that life originated on Earth itself. They believed that amino acids were formed in the volcanic plumes, and the lighting they caused, in the Early days of the planet. Recently, another theory came into prominence, suggesting that life might have had an extraterrestrial origin. Panspermia states that comets delivered the essential building blocks of life, along with water and various gasses. My question is, how did the amino acids form inside the comet? Or did the comets only bring the raw materials like carbon, hydrogen, nitrogen, and oxygen, to Earth, and then prompted the actual creations of amino acids? I just don't understand how amino acids could have formed in the comet...

Answer 1

It's certainly possible, but we'll likely never know for sure.



Comets have been shown to carry organic material including amino acids. So life, or life's builing blocks, may very well have come here on a comet. This idea is called "panspermia".



We can propose likely scenarios for life's beginnings on Earth, but unfortunately we have no way of determinging the "smoking gun". We can only say, "This is possible and that is possible", but have no way of saying, "This is definitely what happened".

Answer 2

"Did life on Earth come from comets?"



Probably not. The extreme conditions and vast distances between us and even the very local other stars make it seem implausible to me.



"Recently, another theory came into prominence, suggesting that life might have had an extraterrestrial origin."



I take that 'recently' in this usage takes us back to the nineteenth century. The idea of panspermia isn't exactly new. It was floating around the literature in the 1870s. Subsequently, a Swedish researcher called Arrhenius was an enthusiast a hundred years ago.



"My question is, how did the amino acids form inside the comet?"



A usual argument is that spores somehow hitched a lift from somewhere or other that already had life, and these seed other planets such us our one. The comet is supposed to deliver seeds of life, not somehow manufacture them.

Comets are chunks of frozen gases, water, ice, dust and rock that astronomers have termed "dirty snowballs." These snowballs, however, may be 10 miles or more in diameter. Comets orbit the sun in a belt located far beyond the most distant planets in the solar system. Periodically, comets break loose and hurtle inward, where they may become visible in the sky.t delivery scenario because it includes all of the ingredients for life — amino acids, water and energy.



Research shows that the building blocks of life could, indeed, have remained intact despite the tremendous shock wave and other violent conditions in a comet impact. Comets really would have been the ideal packages for delivering ingredients for the chemical evolution thought to have resulted in life. We like the comet delivery scenario because it includes all of the ingredients for life — amino acids, water and energy.

When we read of the "world" in the New Testament, we are reading the Greek word cosmos. Cosmos most often refers to the inhabited earth and the people who live on the earth, which functions apart from God. Satan is the ruler of this "cosmos" (John 12:31; 16:11; 1 John 5:19).

The 4 Veda's written in Sanskrit around 3500 years ago gave rise to Hinduism which teaches about Maya – The Malevolent illusion and Samsara – Mechanical Karma REALITY! - The outer Kingdom, empirical knowledge, and according to Christianity - The Angel of Death ~ Seraphims" Keter - Crown Divine Plan.



Reality is merely an illusion, albeit a very persistent one.

Albert Einstein.



There is no greater mystery than this; that being the reality we seek to gain reality.

Sri Ramana Maharshi (December 30, 1879 – April 14, 1950)



Two of the 4 Veda's, dated 1500 BCE translated from Sanskrit as a transliteration by Ramana Maharshi “Tat Tvam Asi” in English is “That Thou Art”, and Prajnanam Brahma (Consciousness is Brahman)

Over 1500 years later Jesus say's, “I and My Farther are One”. Also Luke 17-21 The kingdom of God within you. http://www.angelfire.com/ak2/intelligencerreport/stethoscope.html



To identify with the world as though we and it are one and the same thing, is to buy into empirically derived scientific discoveries, they then become theoretic philosophies.

(Worldly philosophies - Atheism) - Then believe them like a faith, this is to plough faith into material things,

Answer 5

This theory has been offered incredibly a at the same time as in the past. besides the indisputable fact that, it truly makes the survival of existence in the global extra difficult to describe than the different, triumphing theory. contained in the absence of reliable motives to take a extra complicated theory, we will stick to the easier one, that existence began in the global, with supplies available in the global on the time. A theory concerning ailments ought to have an same difficulty: a virus that isn't patterned or "effective-tuned" for the type of existence that exists in the global, ought to have a difficult time invading a cellular that stepped ahead in the global, and taking up its "administration centre". a virus that advanced in the global has advanced in an ecosystem that already contains the DNA fabric of the animal that is going to attack.

Answer 6

You really are a little dim, aren't you? Nobody knows, otherwise there would be no debate as to whether God exists. The theory is that perhaps forms of life arrived already formed, such as bacteria

Answer 7

There are some pretty complex molecules found in dense interstellar clouds and in interstellar dust grains, molecules with a dozen atoms or more.

Answer 8

God made man and earth. Nothing else.
