confirmable life
We live on planet Earth, and basically get all our needs fulfilled from resources we have here. We currently have no use for other planets.
Because (as far as we currently know) Earth is the only planet in our solar system that supports life.
We live on planet Earth, and basically get all our needs fulfilled from resources we have here. We currently have no use for other planets.
Earth is currently the best planet for human life due to its ideal conditions such as the right temperature range, water availability, and oxygen levels. Other planets in our solar system lack these essential factors for sustaining human life.
The only planet known to have water and life is Earth. It is quite possible that other planets orbiting other suns do as well, but we currently cannot determine such details across interstellar distances.
.How do you know that earth isn't the other planet?
There is currently no confirmed sister planet to Earth. However, astronomers have discovered many exoplanets in other solar systems that share similar characteristics with Earth, such as being rocky and located in the habitable zone of their star.
It is not unique in any specific physical characteristic; the only thing unique about Earth is that - as far as we know - it's the only planet to harbor life.
The only one that humans are currently aware of is Earth. No other planet in our own solar system has intelligent life, and there is no conclusive evidence as of yet that intelligent life exists elsewhere.
No planet that we know of other than Earth is capable of supporting life.
Mars is the other planet in our solar system besides Earth that has water.
The only planet that can't be seen from earth is earth itself. Other than earth itself other planet can be seen, however sometimes it might requires use of high technology!
