Answer

1 A GOOD SEAT 2 TEMPERATURE 3WATER SEA

Answer:

Life as we know it is possible on Earth because of its distance from the sun, allowing water to exist in all three states, and in a cycle. If we were closer to the sun (but not as close as Venus), life may still have evolved, but very differently, likewise if we were a little further away.

I think life- supporting planets are common in the universe, but perhaps the amazing biodiversity we see on earth is rare, a result of randomness and luck which has given us a comfortable climate.

Another reason is that the sun is a medium sized yellow star, stable and long lived. Its estimated that 1 in 20 stars are like our sun.

Other factors to consider would be the tilt of earth. If it had none, there would be no seasons, and the Earth would be a radically different place. The seasons are what drives our ocean currents, which are essential to marine (and all) life. Perhaps the biodiversity would be diminished, if life evolved at all. The same goes for the existence of the moon. Many scientists believe that this unusually large and close orbiting satellite helps stabilize the Earth's axis or rotation. In other words, its gravitational pull has prevented the earth from wobbling on its axis , causing dramatic climate shifts. The moon is also responsible for the intertidal zones, which are vast and diverse ecosystems. Consider also what the climate would have been like if the earth had been tilted at say ,45`,and the implications for life. It would have meant that much larger portions of each hemisphere would be subjected to continuous sun in summer, followed by a long, cold and dark winter. Perhaps only simple organisms (if any) could have evolved in such an extreme environment.

I should add that not all life is directly dependent on sunlight. The alien-like ecosystems found around "smokers" in the deep ocean rely on keimosynthesis, and it is thought possible(even probable) that this kind of life also exists on Jupiter's moon, Europa.

When life began, the sun's energy output was about 20% lower than today, and has been gradually increasing since then, and it is estimated that within a billion years the solar intensity will have increased by about 50% on today's value. The distance to the sun may not be so ideal then, and the Earth may experience a runaway greenhouse effect, like Venus, extinguishing all life.

Humans are God's creations and where put here to rule and be keepers of this planet.

ANSWER

its due to whatever you want to believe really as there are any amount of possibility's,

theres never one answer for anything as every person has their own beliefs and ideas on things

ie you could believe evolution- that we are here through millions of years of other creatures changing into other creatures and we were what they changed into, and that eventually we will change into something else too

you could think along the same lines as god, ie a higher being or consciousness gave us life, put us here for whatever reason, could be they were bored or lonely, trying an experiment

you could think god the man in sky version gave us existence for whatever 'his' reason you think acceptable or believable

the scientific facts and evidence go along the lines of evolution,

belief and faith are what keep people thinking god or any other higher conscious being or life created us but there are no facts or true untainted evidence to sustain these theory's,

however some scientists do not debunk the idea of god or higher being as humans need to have belief and faith, even scientists, but they are more in need of proof to fully be able to commit to the belief

personally im an evolutionist, it makes perfect logical factual evidenciery sense, there are examples all over the place

whereas god- man in sky seems preposterous to a person like myself

i am willing and have some belief in a higher conscious as i believe that it is probable for a higher conscious to become into existence due to evolution just like we did.

i certainly do not believe for a second humans are the most important thing ever to happen to the planet,

we are mere lives in a billion lives just like any other creature on the planet, and there are many other 'smart' creatures, ie dolphins and whales

there are many other bigger creatures than us, ie whales

and we are just part of the whole big picture and not the big picture itself. as i like to say

f4

Earth is home to humans, not another species of intelligent animal, because of the atmospheric conditions, the abundance of liquid water, and the heat reaching us is the right amount required.

Who, or what made this planet? What is the purpose of life? And How did living organisms get here? well let's start with the easy answers;

RELIGIOUS perspectivesthey all agree that God,( or Gods) made the Universe and placed us here to test us, to see if we are worthy to get into heaven, after we die, or if we sin badly we will burn in hell. Hinduism, however, states that the vibration sound used to meditate; 'OM' came and the Gods came into existence from that, Lord Vishnu, a Hindu God, told his servant, Brahma, the Hindu God of creation, to create everything. The religions Sikhism and Buddhism evolved from Hinduism so they have similar beliefs. Duration of creation in these stories must be noted, in Christianity and Judaism, genesis of creation lasted 7 days, with God resting on the Sunday, whereas Muslims in Islam, and Hindus believe that it all happened near to instantly, so almost like a Big Bang. How living organisms got here... for most religions, as in the Abrahamic religions, the story is that Adam and Eve ate the fruit from the tree of knowledge in heaven, and were so exiled to live on Earth, and God Created all other beings, and from then on God tested his new human race to see if they were worthy enough to enter his gates of heaven, or if they should rot like Satan, the devil, who causes all the evil in people nowadays. So the purpose of life from this view is obviously to connect with God and get him to allow you into heaven.

and now...

Scientific Answers

As to the theories of origin, the Big Bang theory is most popular, so I will explain this one. This theory itself has many features in it are disputed, like what was there before the big bang, I will go with the most logical, which is that the Universe was minute, extremely tiny, smaller than an electron in an atom, which at the moment is the smallest known thing. Then what happened next is also very much disputed, again, I will write what I think is most logical, so the Universe suddenly Inflates hugely, nobody knows why yet, some say it was a huge old star that went Super Nova, which is ridiculous, as the same people say that the Universe was tiny, so no-one knows why, but the Universe inflates hugely within fractions of seconds, with this hyperinflation is the arrival of helium clouds, or more scientifically known as the various H II region nebulae, and dark nebulae. the eventually 'clump' together, the greater the mass of the forming object, the hotter it gets, once the object reaches 107oC (10,000,000 degrees Celsius/Centigrade) it becomes a star, or more accurately, a protostar, this is the first stage of a star's life. This burns hydrogen, like all stars, near the end of its few billion years of life it runs out of hydrogen and has to burn helium (by burning I mean Nuclear Fusing) to fuse helium it has to get much hotter than when fusing helium, the star gets bigger because the force of gravity is less, far more less than the thermal energy going out, the hotter it gets the greater the thermal energy going out is, so the more it expands, and it starts to turn red as it is fusing helium instead of Hydrogen. It is now a Red Giant. When it fuses helium it forms Carbon Dioxide, when the star reaches the end of its helium storage it can't get hot enough to fuse Carbon dioxide because the temperature required is far too high for the star, so the gravity acting on it at this point is huge since it has enlarged, so when it runs out of helium it loses all thermal energy going out so there is nothing holding the star's shape, so with all that gone the gravity impacts instantly imploding the star completely, and for a split second as the mass of gas smashes into itself, it gets a temperature to fuse the Carbon dioxide, alongside that the Super Nova Explosion scatters it around creating a new cloud of gasses, except this time it's a planetary nebula, also known as a Super Nova remnant. This Gargantuan cloud, thanks to the fused CO2, has been able to form more useful elements like Fe (iron) and MOST importantly WATER.

The human race as with all intelligent life is here as the consciousness of the universe. we are the point at which all Creation has the ability to reflect and examine itself. we are to the universe what the mind is to the body. The infant mind in that we are yet aware of our full potential to mastery over material things.

they would be the ones who carried on god's word. he also created humans to be just like him. so that is why! Alternative answer: We're not. We're just a random, meaningless type of life form that is insignificant from a universal viewpoint. What makes you think we're important? What's happened in the universe that wouldn't have happened without us?

Without any one or more of the following items, life on Earth would shrivel and disappear: -- atmosphere containing free oxygen -- ozone layer in the atmosphere -- liquid water -- temperature which: ==> is near the triple point of water ==> is amenable to the molecular chemistry of life ==> remains within a relatively narrow range over a large portion of the planet's surface

because of water,climate and most important because of the SUN. The light and heat from the sun makes it possible for the life to be created and supported
