Yes, there are 2 billion planets around our solar system and many of them can host different species of life forms beyond our knowledge or understanding.
Well, certainly no intelligent life, anyway. (The only known life at this time is on Earth, which is one of the planets.)
Yes, only on the Earth. We don't know if the other planets have life
No one actually found any human life on any other planets yet, but there is known to be some plant life out on mars.
No. Also, if there is any life on any of the planets, it would not be alien; it would be native.
We don't know about any other other place, besides Earth, that harbors life. But many scientists think that there is life on other planets.
None that are known. Earth is the only place in the universe known to have life and it is highly unlikely that any of the dwarf planets in our solar system have any life.
No
The inner planets all have craters on them. Only Earth has any life that we know of.
At this time we have no evidence of any extraterrestrial life.
So far, mankind has not discovered any life on other planets, let alone intelligent life. There's barely any intelligent life on this planet!!!
Yes, Earth
No life has been detected except on the planet earth.
