Answer: There is much evidence of "extraterrestrial life" but not necessarily living on other planets. The Bible states that millions of beings exist that are not earth bound. It states, "Then I looked, and I heard the voice of many angels around the throne, the living creatures, and the elders; and the number of them was ten thousand times ten thousand, and thousands of thousands . . ." (Revelation 5:11, NKJV throughout).
Additional places in the scripture indicate that the amount of life that is not on the earth is innumerable.
But you have come to Mount Sion (Zion), and to the city of the living God, heavenly Jerusalem; and to an innumerable company of angels (Hebrews 12:22, HBFV).
Some of these angelic creatures have animalistic forms such as an ox, eagle or lion while others have a more humanlike appearance. Many of them have wings with multiple eyes (Revelation 4:6 - 8). They were created before anything else came into existence.
These beings, who have possessed life for countless years, have visited our planet many times (Hebrews 13:1 - 2). They visited the earth and met with Lot shortly before the destruction of Sodom and Gomorrah (Genesis 19). They also talked and ate a meal with the great patriarch Abraham (Genesis 18:1 - 8). None of these otherworldly life forms distorts the Bible's teaching about creation. They, in fact, support it (see Job 38:4 - 7).
Let us now consider the possibility of human-like life on other planets. God reveals himself as the creator of all things that exist everywhere (Colossians 1:12 - 13, 15 - 17). He created our sun and every star that exists, with some so far away that they appear as points of light. He created the various island universes we call galaxies, which have hundreds of billions of stars. He created matter, gravity, force, energy, radiation, colors, angels, spiritual principles, and even time.
Science has so far revealed (from a physical perspective) that NO living beings exist on any planets other than the earth. Science also tells us that living things can only come from things that are already alive. A conscious existence cannot come from inorganic matter. If something is alive somewhere else then God himself would have created it. It would not have come into existence through evolutionary processes.
Life is extremely complex and from a scientific and mathematical perspective, earth probably contains the only living entities that exist in the cosmos. It is highly unlikely, probably impossible, that creatures like us exist anywhere else. Evolutionary science is blind to all of the above because they have rejected the knowledge of God.
Any life found on other planets would still owe their existence to God. If he created conscious, thinking beings on places other than earth, it would not distort the Biblical concept of creation. The Eternal would still be responsible for their existence.
