We read the media reports about efforts to find life on Mars, on various moons in our solar system, or planets orbiting other stars in our galaxy. These reports often give the impression that some form of life can exist anywhere we look in the cosmos. For example, on Earth, we find life in sea vents on the ocean floor and geysers in Yellowstone National Park, leading people to suggest that some form of life can exist anywhere. Add to that the presence of organic molecules in asteroids, and they say that life is out there if we just look in the right places and in the right way.
Journal of Geophysical Research Biogeosciences published a study of 204 soil samples taken from mountains near the Shackleton Glacier in Antarctica. Scientists had predicted that this soil would contain microbes, as is true of soil samples all over the Earth. Instead, they found that 20% of the soil samples, those taken from the higher and dryer locations, had no detectable microbial life. The study seems to indicate that extreme cold and dry conditions can render an area devoid of life. Noah Fierer, one of the scientists involved with the study, said that this might be the first time scientists have found soils that did not support microbial life anywhere on Earth.
The idea that some form of life can exist anywhere in every kind of environment is an evolutionary assumption that is apparently incorrect. We know that extreme cold and dry conditions exist on Mars and many moons in our solar system. Assuming there is life elsewhere because it is so abundant on Earth and some bacteria do well in extreme conditions does not mean there is no limit to where life can exist.
We have said many times that there might be life elsewhere in the cosmos, but if there is, God created it. This is not a biblical or apologetic issue, but these new discoveries indicate that there are limits to the environments where life can survive.
