Thats food for thought, maybe there is a higher power after all.

No. There are a lot of conditions that have to be met before life can develop, and though we probably don't know all of them, there are too many to make complex life on 2 out of 9 planets (and some several dozen moons) a high probability, although it is possible. that complex life could be living within the clouds of a gas giant such a Jupiter and we wouldn't know about it. However, using those same odds, it is also very unlikely that complex life would only have evolved on Earth and nowhere else. I believe that aliens exist somewhere. We may never meet them, but they're out there.

No. It is not strange at all. The other planets are extremely hot or cold. Mercury does not have an atmosphere, the others have toxic such. There is however a small Chance that Mars once did host life of some sort, but when the core of the planet cooled, the magnetic field was lost. This caused the solar wind to erode the atmosphere. That's why there is no life or water there today. The Jupiter moon Europa might sustain life, but it is just speculation...

Strange? no, it is not strange. There are certain conditions that are appropriate for the evolution of life. Liquid water is predominate among them.
Also you are only looking at this (from a stellar perspective) in a very small time frame. There are many theories, that more primitive life can be currently flourishing on a number of bodies within our solar system, and even those that go as far as to believe that a much higher form of life may have developed on Mars eons ago. Mars was suitable for life long before the Earth was, and it is definately a possibility.

I do agree that our lives are very staged and that there must be something behind it.
However, I don't think it is unusual for us to be the only complex planet with life in our solar system, as earth sits in the perfect zone---just far enough from the sun to be the perfect temperature and such to harbor life. Now, if we looked at many other solar system and the planet that would be the equivalent to earth and found no one else supported life---to me that would be a definite sign that our earth is very "staged".

There is a goldilocks zone of every star. A very sensitive radius around it whereby which a first order temperature estimate will show a possibility of large bodies of liquid water to exist on said planet. To calculate this temperature estimate, the formula is T=Ts*sqrt(Rs/(2*r)), where Ts and Rs are temperature and radius of star, and r is the distance from star to planet. The habitable zone (or rather goldilocks zone) is the range of values of r whereby which T can be anywhere between the freezing and boiling points of water. Caution: temperatures are in the Kelvin (or Rankine) scale for this. Why water? Because water in liquid form is important to all life as we know it. It has substantially many favorable unique properties which make a planet habitable. No other substance has been known to demonstrate many of these properties. If you crunch the formula given Earth's orbital radius and the sun's parameters, you get T=280 Kelvin, which is about 7 Celsius, or about the temperature of November in New England. If you crunch numbers for Mars, you get about 240 Kelvin at perihelion. This is about 33 metric temperature difference units too cold for liquid water. If you crunch numbers for Venus at aphelion, you get about 327 Kelvin...or in otherwords 54.5 Celsius. That is hotter than a record high surface temperature for Earth in very unpleasant conditions. This still is in the goldilocks zone though. Water definatly exists as liquid at this temperature. If distant astronomers from another planetary system discover the solar system, they will be very happy, and think they got two planets in one system that could have life. BUT, we know more than just the orbital characteristics of Venus, and we can give a more educated reason knowing about its atmosphere. It has a runaway greenhouse effect which actually makes it the hottest planet of the solar system. It has thick sulfur dioxide clouds and carbon dioxide, and it traps the heat from the sun not letting it escape back to the cosmic background. Hopefully our Earth will not someday end up like Venus.

I don't think its weird at all that our planet is the only one in our solar system that contains life. After all there are many other stars in the universe that have the possiblity of being another solar system's sun. With that possiblity, there could be another planet that is just in the right distance to support life. But you have to remember that it might not be life that would make sense to us. They could be adapted for warmer or colder temperatures. Humanoid life needs the right distance to thrive.
But with all the possiblities of other stars being suns - I dont think its strange at all. We're the only ants on this block but in the city, there are many other blocks. We just haven't been able to explore the whole city yet.

I believe that this question is being looked at all wrong. Our bodies were created to be suitable for Earth not for Saturn or Jupiter or Mars. We were created to only withstand a certain temperature and to need water. Other planets may be suitable for other life and have otherlife forms on them, the issue is that we cannot create the correct satelites to go find them due to the conditions that the other planets are on. It is very possible that on Pluto there are other forms of life who were created to live in darkness.

No, not strange or staged at all.
If it wasn't the case we simply would not be here.
Take possible life on Mars...
There is evidence that microbial life-forms may have evolved there. However, planetary conditions changed so now its just a cold empty rock. Staged, planned?? Not at all, there is no rhyme or reason it just can happen if conditions are right/wrong. Nothing magical about it.

The Earth wasn't created to harbour life, life evolved to suit the planets environment.

If this planet didn't support life you wouldn't be asking that question.
Life is so adaptable that the probability of it surviving somewhere in the universe I imagine is very close to one.
