The search of life on other planets is getting more sophisticated. The ability to detect signals across many other frequencies is expanding. One scientist says signals could be found by 2035. He is not certain yet there are any out there, but new detection systems are pushing into the previously unknown.
It is fun to speculate about life on other planets and even in other solar systems. According to the link, there are planets circling other stars that, like those circling our sun, that are too close and too hot, to far away and too cold and withing the range of heat and cold tolerable to life as is earth.
Suppose a form of life is discovered out there and we learn enough about it to know it has something like brains and comprehension. The Bible tells us we humans on earth are his favorites. Would the faithful decide God did not like these other creatures as much as he loves us? Or, would they simply not believe regardless of the evidence this other life exists.
To the non believer life on other planets would change nothing. The non believer sees humans as simply part of the natural world and nothing or nothing less. Humans exist now because of fortuitous events that began life and it developed into humans. Someday the sun will burn out and the favorable circumstances and the humans they brought about will be gone.
Neither life on earth nor life in outer space has anything to do with religion.
