Is There Other Life in the Milky Way Galaxy?
We know that carbon-based life equipped with DNA has certainly taken root in our Milky Way Galaxy, specifically on Earth. There are strong indications that life also took root on Mars and probably on millions of planets. Therefore, it is certainly possible that throughout our galaxy and even in different galaxies DNA/carbon-based life exists. It is also possible other galaxies harbor completely alien and unique, non-DNA, non-carbon based life.
Our Solar System is near the bottom of this depiction of the Milky Way Galaxy which is comparatively flat like a huge disc. Our Solar System is on one of the outer arms of our Galaxy, where our own sun and planet are located. Therefore, those planets and stars closest to our own would be more likely to host life which is similar to life on Earth as compared to those much further away. Life on Earth is probably just a sample of life’s possibilities. It seems logical to assume Galaxies the furthest away from us would have organisms different from Earth. Planets circling stars within the inner arms of the Milky Way Galaxy may harbor life forms considerably different from those in the outer arms. The Bible says humans were made in the image of God. “God created all things by Jesus Christ: to the intent that now unto the principalities and powers in heavenly places might be known by the church the wisdom of God.” Ephesians 3-10.
The intelligent life forms closer to the center of our Galaxy are much older and most likely far advanced compared to Earth’s technology and are likely visiting us. Their suns or planets may have dire problems and the advanced extraterrestrial intelligence may be searching for a new home planet. There is some evidence our visitors are joining us here on Earth. The US has millions of illegal aliens, perhaps some are from other planets.
The nature of life on other planets, at least in our own Milky Way Galaxy, likely includes single celled organisms. Meteorites coming from Mars called carbonaceous chondrites carried large numbers of bacterial microfossils billions of years old. It seems likely life is spread throughout the universe by similar comets and meteorites that also bring water. Stars give off light and warmth, and rocky planets contain minerals, metals, and a variety of gases that eventually form atmospheres that support various forms of life. We can predict millions of planets, particularly those located in habitable zones, are crawling with various forms of life that eventually create advanced forms of life.
