We don't know if there is no other life in our solar system. Have you been there? I haven't we don't know. We have also never really looked with the intensity we have here. Just because we have dropped a robot in on spot on one planet doesn't mean there is no life on the whole thing.
Think of it this way, If I dropped you in the middle of Death Vally and said find life right where you are, you'd be hard pressed to do it. But then to assume that since there is no life on this spot there isn't any anywhere? well that is just plain ignorant.
As for calculating the odds, the Drake Equation estimates 100,000,000 other planets with sentient and intelligent life in the universe.

We do not know for a fact that there is no life anywhere else in the solar system. We have only begun to search for it.
We now are nearly certain that Jupiter's moon Europa is covered in a salt-water ocean and is covered by an icy shell. If this is true, then there could possibly be life there. Tidal forces from orbiting Jupiter have prevented the ocean from freezing over and may even be providing enough heat for organisms to survive. Ganymede, Jupiter's largest moon (and the largest in the solar system) may even have water.
There is also the possibility that life used to exist on Mars. We won't know for sure until people actually go there, however. The chances of a probe landing in just the right location and digging in just the right location to just the right depth to find evidence of past life are impossibly high.

Because God wanted it that way. Or at least, he wants us to feel special, since we really don't know if there aren't other life forms elsewhere. We really haven't surveyed the planets thoroughly enough to know anything conclusive even about our own solar system. They just reclassified Pluto as a non-planetary body so how much can we really say we know even about our own solar system?

In The Princess Bride, Westley says to Buttercup, "This is true love. Do you think this happens every day?"
The odds of life happening are astronomical, thus we will have to search the astronomical universe to find it in other solar systems. I am thinking we will if we aren't annihilated by global warming, nuclear bombs, overpopulation or some naturally occurring disaster such as a giant asteroid first.

if the word life means (humans) then the answer should be
- the lack of oxygen on any other planet
-the lack of water
-the distance from the sun (hot or cold)
-the number of moons that could empower the gravity

OUR planet is the only one in the habitable zone with all the necessary requirements to support carbon based life forms.

Cause earth is the only place that has liquid water
the rest of planets is either ice or steam

How do you know life doesn't exist on any other planet? "Life" is not just defined as being a **** sapien -- perhaps there are microorganisms on other planets. There could be organisms out there yet unknown to man.

That hasn't really been proven yet. We haven't visited every planet out their to know for a fact.

because of there places away or toward the sun which could possibly mean other solar systems have life maybe just like us or with aliens whatever you never know
