Is the Earth the only planet in the universe that can support life?

Answer 1

So far, Earth seems to be the only planet in our solar system with abundant carbon-based lifeforms. There are likely some remnants of such life on the other solar planets, if only as transplanted by meteoric collisions with Earth. It is unknown if the conditions for Earth-like life exist elsewhere, or if any actually developed in those conditions.

Life has not yet been found anywhere else other than on Earth. So, to answer your question - to the best of our knowledge to date, yes.

Answer 2

Within our solar system, yes. Earth is the only planet that can currently sustain life on its surface. However, there are billions of solar systems out in space... we live in the milky way galaxy, and there are millions of other galaxies out there. I think that it would be a lie to say that Earth is the only planet that has living creatures. Think about it, have you ever seen all the stars in the night sky? Each star is billions and billions of miles away. We haven't even seem half of the stars out there yet!!

Answer 3

We really don't know. If I say yes or no, I am simply lying to you.

There are more than 10 billion trillion stars in the universe and more than 80 billion galaxies. Since, we are the product of evolution. It is certainly possible that evolution would occur in other solar systems that are similar to ours. At this moment, scientists are studying a group of planets named Gliese 581 b, c, d, and e. Their solar system seems to be promising. Gliese 581 d has a great chance for hosting life and it is about 20 light years away.

If we don't find anything at this point, it does not mean that the answer is no. We can never make a full judgment about all the 80 billion galaxies and conclude that there is no life.

I hope that this aids as a start for you.

Answer 4

Earth is the only planet in our Sun's solar system that has anything living on its surface.

Concerning planets in the systems of other stars, although many hundreds of them

have been discovered, we can't observe any of them closely enough yet to determine

whether or not there's anything alive on any of those.

Also, we have no reliable evidence that Earth has ever been visited by living beings

from anywhere else.

The only possible, completely-true answer to the question is: We don't know.

Answer 5

It is certantly the only life form we are aware of. The various claims of extra terrestrial visits to earth appear, in all cases, to be unbelievable.

Answer 6

It is the only known planet that can support life as we know it. All other known planets are either too cold or too hot, lack liquid water, and lack atmospheric oxygen.

Answer 7

No one knows for sure but it is unlikely Earth is the only planet in the universe that can support life.

Answer 8

Yes, its the only terrestrial planet
