Those who believe life evolved on the earth usually see it as virtual ‘fact’ that life has evolved on countless other planets. Discovering life on other planets would in turn be seen as confirming their evolutionary belief. But even many Christians think, ‘God must have created life elsewhere, otherwise this enormous universe would be an awful waste of space.’ This seems to be the major underlying reason why people think that there must be other life 'out there'. However, our thinking should be based on what God said He did (the Bible), and not what we think He would, should or might have done. If you struggle with this question you are not alone. I venture to say 99 out of 100 people if asked this question will say yes. There are other humans/aliens ‘out there.’ May I suggest to the believer and non-believer alike, the earth and we humans are actually very unique, and the only humans that exist. Let’s read Psalm 8:3-9 written by King David through Gods inspiration.
3 When I consider Your heavens, the work of Your fingers,
The moon and the stars, which You have ordained,
4 What is man that You are mindful of him,
And the son of man that You visit him?
5 For You have made him a little lower than the angels,
And You have crowned him with glory and honor.
6 You have made him to have dominion over the works of Your hands;
You have put all things under his feet,
7 All sheep and oxen—
Even the beasts of the field,
8 The birds of the air,
And the fish of the sea
That pass through the paths of the seas.
9 O Lord, our Lord,
How excellent is Your name in all the earth!
Man’s uniqueness in the Universe is implied in Psalm 8. When David reflected upon the splendor of the heavens, he wondered: ‘What is man that Jehovah has so benevolently blessed him with all this marvelous creation?’ He appears to suggest that man stands alone in the Universe in this regard. The great scholar George Rawlinson once noted that the thought that he who made the heavens should have such regard for humanity “is well nigh overwhelming.” Thus, rather than suggesting that man is but an insignificant speck in the Universe, this passage reveals that the Lord has bestowed a signal honor upon him who is created in his very image (Gen. 1:26).
Next, God appointed man to have dominion over the creation. Humanity, because of sin, has failed to perfectly achieve that task. Ultimately, however, the epitome of manhood, the Lord Jesus, will demonstrate his supremacy over the entire creation. This appears to be why the writer of Hebrews gives the 8th Psalm a messianic application (cf. Heb. 2:6-8). We do not believe, as some allege, that the author took the original reference out of context and gave it a meaning alien to its intended design. Rather, the Holy Spirit, who inspired both writers, saw a partial application to man, and then an ultimate fulfillment in the Son of man.
