Answer: Abiogenesis
The most commonly accepted scientific hypothesis for the origin of life is that life came into existence through a series of chemical processes occurring on pre-biotic Earth. Such processes may or may not have utilized complex chemical molecules transported to Earth's surface by comets. Beginning with discoveries such as the Miller-Urey experiment, there has developed scientific evidence that it was at least possible that natural processes of heat and lightning in the first billion years on Earth could have formed organic compounds needed for life to begin. There remain numerous conjectures as to what pathway lead to the first self-replicating entities resembling cellular life. Abiogenesisresearch continues to produce new insights.
This answer is but a small introduction to a large topic of debate.

Answer: God
God created everything in six days. Read Genesis 1 and 2 in The Bible.
Answer: Extraterrestrial
There are numerous conjectures of extraterrestrial sources of life on Earth. These theories have a variety of elements. Some hypothesize life starting on Earth with extraterrestrial microorganisms, but others conjecture more complex life forms. Some theories (transpermia) describe how living microorganisms or spores may have have been transported throughout space by natural processes. More elaborate conjectures involve delivery of life forms to Earth by extraterrestrial beings.
Some scientists support theories of extraterrestrial origins. The scientific motivations include the difficulty in explaining the original creation of DNA and complex life in such a short interval as the few hundred million years of Earth's existence. The discovery of meteorites with bacteria-like fossils added stimulus.
No one really knows for sure
God did it. A deity created all life and matter from absolutely nothing in one very short expanse of time, at some point not far removed in history.
Scientific ViewStuff happened. Life appeared. In more detail, the combination of elements in the correct conditions, combined with a large amount of energy such as a lightning strike or the heat from a volcano, gave rise to somewhat complicated chemical species. These then reacted in similar conditions and formed even more complicated chemicals. Fast forward a while, and these chemicals combine in ways that result in replication and growth. After further development, they become living cells that can grow, respire, consume and reproduce.
About 6,000 B.C. God created the heavens and the earth! He loves you!
As per the Quran (the last and final testament from GOD in Arabic) which was revealed 1430 years ago and preserved as it was revealed, gives many scientific facts which were only discovered recently.
It mentioned about the begining of the Universe saying that Earth and Heavens were joined together and GOD splitted asunder. And Earth and Heavens were created in 6 long periods (the Arabic term ayam means either day or a long period). When Adam was commanded to circulate around the KAABA house (now known as in Makkah, Saudi Arabia) by the guidence of angles, it was mentioned that the coming of the Adam on earth is too late (meaning on the very last moment)of earth life.
So, if we estimate that the earth life of Adam is about 6000 years then you can imagine the beginning date of the earth. It should be many many thousands years ago.
As per scientific research the life of the 1st human like species is as old as 120 to 200 thousands years, the most likely human life on earth can not be more than 120 thousands years old.
Again, as per Islamic facts (from Quran and Hadiths) the number of messangers sent were at least 124000. However many messangers were sent at the same also. We can estimate from this that (124000/4/200)*50=7750 is the years that Adam started on earth.

Subsequently leading to rain from the cooling making bacteria which then evolved into different species such as dinosaurs in triassic period. Leading to evolution of primates into
Homo-Sapiens and human beings.

How many year does the earth living?
Although one can argue whether or not Earth is actually 'alive', science shows that Earth is 4.6 billion years old.
How many planets in this solar system support life?
As far as we know, Earth is the only planet that supports life, but there have been many studies that show that some other planets have either supported life previously or could be capable of supporting life.
Can the sun get too hot?
Not really but it will expand at the end of its' life and will engulf the Earth as well as many of the planets.
Where do astronomers think that the moon came from?
Huge rock debris hit the molten surface of early Earth, creating smaller rocks that formed some what rings around Earth. After a long period of time, with the help of gravity the rocks fused together to form the moon. There are many theories to this question.
Why is heliocentrism important?
It was the first theory that said that the universe does not revolve around the Earth; instead we revolve around the sun. It discredited many people's theories and modern belief at the time. It is also the proven theory that we believe in today.
Do scientist debate on the age of the Earth?
scientist do debate in discussing the age of the earth because there is many theories that saying when is the earth began or made
Since life began on Earth many blank have vanished and many new ones have appeared?
lol i have mr.berlin too -_________-
How did life appear on earth?
Christians and scientists have different ideas about this. Christians believe, quite simply, that God created everything on the Earth, from the smallest microorganisms to the gigantic redwood trees and blue whales. Christians refute that life could have occurred just by chance. Scientists have different theories about the origins of life. Many believe in a "big bang" theory, but there are many different theories out there, most of which have life arising from "spontaneous generation".
What is the situation when earth was be created?
nobody knows for sure there are many theories
Why was there no life on earth when it began?
earth was a ball of lava and rocks a medder hit and the lava in rock floow off and became a ball wich is the moon now and the earth cooled because it rained for many many years
How many times did the Earth orbit the Sun between 140 Ce when Ptolemy introduced his theories and 1543 when Copernicus introduced his theories?
1403
How do you explain the age of the Earth?
The age of the Earth depends on many things, But first choose a one of the theories of how the Earth was created and go from there. There are so many different theories, be careful some of them could offend others, that depending on which one you choose your answers could dramatically change.
Do scientists know how the planet Earth started?
No, but there are many theories. The big bang, God, and many more.
Critique two scientific models that explain the origin of life?
One scientific model is PSM which theories that the origin of life began from molecules found in the ocean. Another scientific model for the origin of life is BM which believes chemicals surfaced on top of the water. Both theories are hard to prove.
Where is life suggested to begun?
Most scientists believe that after the Earth was formed simple bacteria began to appear as the Earth cooled. Then the bacteria evolved into photosynthetic bacteria, a very simple form of plant, and into other single-celled organisms. These gradually became more complicated as they evolved over millions of years into plants and animals, and eventually after many more millions and even billions of years they eveolved into the plants and animals we know now. Other people believe that the world was created by God or gods, and there are many, many religious theories as to the creation of the world. There are other theories, both religious and non-religious but none have been proven so the matter is open to speculation.
Are theories ever changed?
Theories are changed constantly. In fact, many known theories today are only theories from that of someone else only with an improvement. Many scientific theories for example are developed that way. Take this for example, many thought the world was flat, that theory developed (changed) to the fact that the world is round instead of flat. Current theories that are changing daily-- "How was the universe formed?" "How did life begin"? "Was there ever life on Mars"? "What is all that DNA for?" "How do we make more efficient solar cells?" "What will happen with global warming, and how can we modify it?"
Why does the earth live?
If you are asking, "Why is there life on earth," sadly no one can give a 100% certain answer, although many theories exist. The most common scientific beliefs are that early life on the planet arose through complex random chemical interaction in the primordial sea, possibly using energy from geothermal vents or lightning strikes. At the same time religion offers countless answers of its own as to why there is life on earth.
