Are we alone, or Is there another Earth out there somewhere?

Question

Are we alone, or Is there another Earth out there somewhere?

Answer 1

so many rare things had to happen to make earth as it is today. for example the collision with thea, the planet that collided with earth when earth first formed is thought to have resulted in the moon and making the earth mush more massive it also made the earths core start to rotate which gives earth the protective magnetic field, also for a planet to support any kind of intelligent life it must have a massive planet near by to attract meteors away from it like jupiter also the earth is at a perfect distance from the sun for liquid water. But there are a lot of planets out there so I guess it's possible

Answer 2

Yes, there's a possibility that there is another Earth, another planet that there is also animals, plants.... and also HUMANS..

The universe is really, really wide/big.. You can't tell that there is another living things, like Aliens for example.

Answer 3

As far as I know, we're the only Earth in the universe. But I'm pretty sure that there might be another planet or solar system that holds life. It might be a while, maybe about the time we actually find out more about time travel...

Answer 4

Yes, there's me.

I think the possibility of life elsewhere is almost certain. As Woody Allen stated, "If we were the only living beings in the whole Universe, that would be a lot of space wasted". The thing that many people misconceive is the word 'life'. What exactly is life? Many people will assume that living things out there are some high-tech, technological beings which are coming to destroy Planet Earth. Life can be anything from a simple piece of bacteria (of which finding I believe will be more feasible). The nearest star to Planet Earth if we exclude the Sun is Proxima Centauri. One day, maybe just one day, Man may be able to explore that in the hopes of finding something tantamount to himself.  

Answer 5

Yes there is another Earth BUT not in our universe but in parallel universe. You should better call it ANTI-Earth.

Answer 6

I think there is another Earth we have so many planets we have not reached yet, don't you think there is? I do

Answer 7

With the universe being as vast as it is another earth-like planet is inevitable.
