Planets closer to the Sun than Earth are too hot to support life and planets further out are too cold.
Some planets can not bear life because they are too close or too far form their mother star or stars. Some of them are too gaseous, others are too hot or too cold, and others do not have atmosphere or lack water or nutrients nutrients to grow living beings in them. Life, as we know it, can exist only in planets with the proper conditions for it.
because the temperature is simply too hot or too cold or we can not have the resources we need
They are either too close to the Sun (Mercury, Venus), too far from the Sun (Jupiter through Neptune), or could have supported life, but lack the proper atmosphere (Mars).
Temperature wrong, atmosphere wrong, not enough water.
Because they are like other life planets they might be able to produce more life when Earth explodes.
what molecule do scientists look for when they are investigsating the possibility of life on other planets
No one actually found any human life on any other planets yet, but there is known to be some plant life out on mars.
So far, mankind has not discovered any life on other planets, let alone intelligent life. There's barely any intelligent life on this planet!!!

NO- People have found water on other planets but there is no life there.
There are several books that deal with life on other planets. Some titles include Is There Life on Other Planets by Gregory Vogt, and The Mystery of Life on Other Planets by Chris Oxlade.
Life on Other Planets was created in 2001-10.
Earth's scientist have not found life on other planets to date.
Emanuel Swedenborg is the author of Life on Other Planets
Space astronauts went to the planets to be sure there is no life on planets
We cannot say if life exists on other planets or not. We are trying to work it out.Just because there is no evidence does not mean that there is no life on other planets. We are trying to work out the answer but the answer maybe, YES.
scientists can't really find if there is life on other planets
i think that yes there so can be life on other planets because among 100,000 planets ours is the only one with life on it. x<Laura>x
There is life on other planets. Imagine, there are 1000 planets in the Universe for every grain of sand on the earth. That's how many planets there are, so scientifically, the chance that there must be life on other planets as well is much greater than the chance that there is no life.
Yes,Other planets could scientists believed some life were on other planets and signs of life
Yes, only on the Earth. We don't know if the other planets have life
