You folks have such a limited view of God's marvelous creation.
Now that I have stoked a flame, let me explain myself.
What if all that there is, is here for the specific reason to support life on this one planet? Frankly I can't see a just God creating life as we know it (as angelic life is not life as we know it) only to wipe it out when all the elements are melted with fervent heat by the judgment of almighty God. (2Peter) The distance of the nearest star alone would take 5 years to travel to. And that system is a binary star system that emits such tremendous radiation to render any planet(s) that might be near it sterile. If there was life there and we wanted to meet them you would have to have a "Wagon Train" of ships to carry needed supplies to sustain life there and back again. We would have to carry enough of the air we breathe, the food we eat and the water we drink to get us 10 years worth of traveling. Not to mention the fuel, I seriously doubt that we would find an Exxon any where past the moon. Even if we were to try to meet them half way the armada of sips needed would use all the resources that man has ever produced to send just three men on a 5 year round trip.
Upon further reflection of mine above what if, think on this, The Earth is the only body in our vicinity of the universe that has an 'almost twin' orbiting it. While the Earth does bare the marks of collisions it is the moon that has gotten the worst of the deal. One third of the Earth's mass, the moon's mass attracts most of the objects that have a collision trajectory with Earth.
The Planets of the inner solar system also protect the Earth from much of the energy thrown from the sun. They orbit the sun on the same orbital plain as we do. Mercury aligns up with our orbit between us and the sun several times in our year around the sun thus absorbing much of the sun's radiation that is harmful to our way of life. Venus aligns up with our orbit 5 times in our year doing the same thing that Mercury does. What radiation is left over is deflected by the VanAlan magnetic belts. (MagneticPoles should be able to validate this info:tongue3: )
The outer planets are so massive that they actually attract other bodies that are headed our way. Jupiter, just a few years ago had a comet smash into it. That comet could very well have had our names on it.
As for any other planet out there only God knows the purpose for which He alone has destined for it. If He has put life there, that is His business and who am I to guess why. It, IMHO is for sustaining life here.
Think also on this one, Why does God commit only one chapter in His Word to His marvelous creative work and all the remaining chapters to His seeking man's repentance? He begins by looking and calling for Adam and ends Revelation by calling again for men to repent. It seems therefore that God has placed more importance upon His redemptive plan than we do on speculating about life..... out.... there.
