Is life unique to earth? Or is other life in the universe? Is there water throughout the universe? Well, the odds are extremely good that both life and water are scattered throughout the universe. And the odds are not bad that there are some forms of both life and water outside our planet within our solar system.
Scientists know that meteorites and comets both have water. It is possible that many planets in the universe have water and potentially life. In the future, we should be able to examine distant planets and determine if water and potential life exists. At that time, odds makers in Las Vegas may place a 2:1 chance of there being other life within our galaxy.
Scientists used to believe that water on earth came from comets. Certainly, some water did come from comets and meteorites crashing into our planet; but since there is more water inside the earth than in the oceans and on land, we must conclude that most of earth’s water came from some other source.
One theory is that most of our water came when our planet was evolving through accretion from water-laden bodies pushed from the ice-zone into our more temperate climate zone by Jupiter as it acted like a snow plow. Jupiter probably meandered from the colder zones pushing proto-planets with frozen water into the inner circles where the rocky planets developed.
Therefore, Mars, Earth, Venus, and Mercury all benefitted from the water opportunity. However, the sun was too close to Mercury and simply burned off its water. The water on Venus may have evaporated into higher elevations with runaway global warming until it was blown away. The water on Mars probably lost out to the sun’s radiation without protective magnetic poles. So, only our world retained the water.
Where would other water and life be hiding in our universe? Probably, life will be found on at least one of the moons of Jupiter or Saturn. The gravity forces of Jupiter and Saturn, kneading these moons like a rolling pin on bread, creates geysers and probably black smokers in their deep oceans, which could easily become an environment for extremophiles, just like it is on earth.
And if water is found throughout the universe, which is logical since it is more common than we once believed, then life should also be more common in the universe than we once thought. I would be very surprised if life did not flourish throughout the universe. And we would be remiss if we did not mention the possibility that some forms of life could exist even without water.
So, does life exist throughout the universe? I don’t know, but I would say that it is more likely than not. And does this mean that there is no God? Of course not… it simply means that God’s creation is much more complex than we originally believed. And it means that with hundreds of billions of galaxies in the universe, we should stop being so anthropocentric.
