Why only Earth has been chose to sustain life? why not only other planet?

Answer 1

Earth has not been chosen. Our existence is the result of countless random occurrences that combined to make what we are today. Think of this, to be a the right distance from the sun, not too close not too far. To have an iron core big enough to produce a magnetic Field strong enough to protect us from the sun's radiation. To have enough water to make oceans, thus creating weather. To have a moon of the right size and distance to produce tide and stir everything up. And presto! You have life! Do you know, by the way, that our moon is the result of a collision many millions of years ago between our planet and a planetoid the size of mars? The earth was totally destroyed and that's how we ended up with the moon and a big iron core at the center of the earth.

Answer 2

For the moment lets set aside the religious aspect of your question.
What is your definition of life? Is there proof that there is no other planet that sustains life? Life in what form? If you mean human life as we know it, think for a moment what it takes to sustain human life. Oxygen, water, a climate that is survivable, a reliable food source, etc. etc.. Other life may have other requirements ie; perhaps no need for oxygen, maybe other life forms can exist in a climate far more severe than that of the Earths climate. Which brings us back to : Is there proof that there is no life form on other planet(s)?
Perhaps a little research on the 'net would provide you with a more thorough answer......
Returning to the religious end of the "debate", a great deal of the answer rests with your personal belief structure. The answer to you question, with your belief in mind, has been the subject of continuing discussion from the time the existence of other planets was known, as is the answer to the question What is life?
Most likely these discussions and debates will continue as long as there is a human race. And the question : Is there life on other planets?
All this is part of what puts humans in a different category than other life forms, the ability to talk and discuss, debate, disagree and the ability to agree to disagree.
Now get a glass of warm milk and some cookies, relax and think about just how small, but how important you are, as a part of it all.

Answer 3

That is a freakin' easy question! Earth has water, carbon, an atmosphere, and has the right temperature to support life. The other planets have no water, no carbon or not enough, no or thin atmosphere, and is either too hot or too cold.
Inner Planets - - - -

----Mercury----
1. Too hot on the side facing the sun, too cold on the side facing the opposite direction.
2. A very thin atmosphere.
3. No water and carbon based molecules.

----Venus----
1. Too hot, about 1000°F
2. Poisonous gases
3. No water
4. Filled with volcanoes

----Mars----
1. Might be possibe to have life but can be cold there

Outer Planets - - - -

----Jupiter----
1. Poisonous gases
2. A LOT of gravity ; you would not be able to stand up there
3. No water or carbon based molecules
4. VERY cold
5. Powerful storms

----Saturn----
1. Poisonous gases
2. A LOT of gravity ; you would not be able to stand up there
3. No water or carbon based molecules
4. VERY cold
(Just like Jupiter)

----Uranus----
1. A LOT of gravity
2. No water or carbon based molecules
3. Poisonous gases

----Neptune----
1.1. A LOT of gravity
2. No water or carbon based molecules
3. Poisonous gases
4. Powerful storms

Dwarf Planets - - - -

----Pluto----
1. Atmosphere too thin
2. No carbon based molecules
3. WAY TOO cold


Mars may be the only planet that can support life.
Pluto's new name is now "134340". Pluto is demoted from being a planet.

Answer 4

We don't know for an absolute fact that Earth is the only planet to sustain life. It's a big universe.

Answer 5

We know there is life on earth. It is natural to ask how this life arose( or evolved).Especially because the conditions that sustain life ( oxygen in atmosphere) are different from the conditions that prevailed when life formed ( hydrogen in atmosphere).

It is NOT possible to answer the question as to what conditions are needed to form life. We can only discuss how this life formed.Can life form under different conditions? Probably yes. But we cannot even imagine any other "type" of life.

Answer 6

How conceited you are to think that, human! There are many water planets outside our solar system that can sustain life, chances are, you won't have to worry about alien invasion just yet. But don't ever get the notion that Humans are the only intelligent life out there again. Space goes on forever, there could be alternate universes, there are such things as ghosts. We are not alone. (And no, I'm not a crazy alien hunter, I'm just rational.

Answer 7

It is not. Earth is one of the more recent planets to develop life. It is a really big universe, with untold numbers of galaxies, each of which contains millions of star systems. In this galaxy there are well over 14 million planets with life as you would define it, a number of these have evolved life that you would consider of higher intelligence. Of these, many of the evolved lifeforms are well advanced beyond the human race here on earth.

Answer 8

Haven't you ever heard the saying; "The thirds the Charm?" Which planet are we from the sun? Kidding really. You really can't be for sure what was and what really is. There may be those capable of hiding their presence and other living planet right here amongst us in our solar system and Milky Way galaxy. Are we ready for the real truth yet? I think so.

Answer 9

Chose?


There could be tons of other planets out there that sustain life.


In our solar system there are no others, mostly because they are all too harsh to have life on them, other than possibly mars. I mean, mercury is far too hot for life, venus is too unstable; acid atmosphere...juipter and saturn are all gas, and their moons are too cold to host life...

Answer 10

Why was your head chosen to be on your shoulders? It wasn't, it just worked out that way.
There are probably billions of planets orbiting countless stars, we haven't even discovered if there is life on the first 8 nearest us yet.
