The only planet we know for sure today is the Earth.
We know that the other planets are either too cold, too hot, or have been observed to have no atmosphere to support life.
It is only on planet earth that we have observed actual life.
It is not impossible that primitive life can still be found on other planets in our solar system, but it will likely be very extreme bacteria etc. Complex life like multi-celled organisms do not exists on other planets in our solar system.
We do not know for sure if complex life exists on other planets outside our solar system. The primary reason that we do not know, is that we have not been able to observe planets outside our own solar system.
That is not currently known.
Earth is called a life sustaining planet because it has life on it, and is currently the only known planet that supports life.
As far as is known there isn't one. Certainly there is no other planet in our solar system capable of sustaining life. It is quite likely there are other planets elsewhere which could support life but we do not have the ability to either find or travel to them.
An animal, insect, or human whose body can sustain the growth of a pathogen is known as the pathogen's host.
Earth is the only planet currently known to have life.
Earth is the only known planet that contains the necessary elements and life sustaining environment for life, as we know it, to flourish
Earth is the third planet in our solar system. Of all 8 planets, earth is the most unique in that it is the only planet with liquid water and the only known planet currently sustaining life. It is the largest planet before the asteroid belt and its atmosphere is a perfect enough distance away to maintain a liveable temperatures. Did you know that Saturn's moon, Titan, is the only known moon and planet-like body with liquid water? ~Apple Juice
If you wish me to tell you a fact about the Earth, then i will happily oblige: The Earth is currently the only planet known to man that has an environment capable of producing life.One important fact about Earth is that the planet has the greatest density than all others.
It's currently not known if Infernape is capable of mega evolving.
Earth is the only planet in our solar system known to support life as we know it, due to its unique combination of liquid water, atmosphere, and moderate temperatures. It also has a diverse range of ecosystems and environmental conditions that make it ideal for supporting a wide variety of organisms.
Currently, there are no known planets besides Earth that have food sources capable of sustaining human life. However, there are ongoing research and exploration efforts to determine the potential for growing food on other planets, such as Mars, through techniques like hydroponics or controlled environment agriculture.
Earth is currently known for being the only planet in the galaxy that can sustain human life. It is also known as our home.
