Do you think it’s at least possible that God created life on other planets?
The Author of Life
In the beginning, it says “God created the heavens and the earth,” (Gen 1:1) and everything else for that matter, and of course, that includes all lifeforms; mankind included (Gen 1:27). When the Apostle Peter was preaching the gospel to the crowd, he told them, “you killed the Author of life, whom God raised from the dead. To this we are witnesses” (Acts 3:15). Not only is Jesus the Creator of human life, He is also the one Who brings eternal life. Either way, it’s all about Jesus. You can’t even get past Jesus to God (John 6:44). Whoever believes in Him already has eternal life (John 3:16), but whoever rejects Him has an eternal death waiting (John 3:18), and with the wrath of God abiding on them (John 3:36b). Before asking the question of whether there is life on other planets, ask ourselves this? Have we been born again (John 3:3-7), otherwise, we cannot enter the kingdom  (John 3:5), not to mention see it (John 3:3)!
The Wasteland of Space
Many claim that life came from a foreign object from space, like a meteorite or asteroid that broke of and landed on the earth, but the question is, where did that life come from? Well, they say, “from another planet or solar system,” but that begs the question, “Then where did that life come from?” It’s the infinite regress that never answers the question about where life began in the first place, or where life came from. Evolutionists don’t include that question as part of their theory, mainly because, they can’t answer it; in fact, no man can but God and He has answered that, but most refuse to believe that only God created life (Gen 1:1; Acts 3:15). Many scientists believe that there is probably life out there on other planets, but even if that’s true, that doesn’t discount the fact that God is the Creator of that life, no matter where it’s found. Just because there is life elsewhere, doesn’t mean the Bible isn’t true or God doesn’t exist. It has nothing to do with that. It has everything to do with ascribing God as the originator and giver of life.
The Probabilities of Life
Did life arise by chance? If there are the right conditions of proteins and enzymes being in the right place at the right time, and there is a cause (i.e. lightning,) could life have arisen by sheer chance or coincidence? We know that spontaneous generation (abiogenesis) has been rendered obsolete today. All we are left with about the origin of life are new theories. Some support the idea of ‘life’ originating spontaneously, from non-living things, but before we talk about enzymes and proteins, aren’t they alive too? Yes, because proteins are large biomolecules, or macromolecules, and they consist of one or more chains of amino acid residues, so we can’t even talk about how life arose until we understand that it couldn’t have spontaneously occurred on its own because an axiom of science is “life comes from life” and not from non-living, inorganic matter. Non-believers want us to believe that we’re just a random accident of time and chance because that would push God out of the picture (with their guilt) as the cause. And they don’t want to be accountable to God. Neither does Richard Dawkins who actually admits in his book, Climbing Mount Improbable, that “The original replicator probably was not DNA. We don’t know what it was” (p. 261), and says the odds for life evolving on its own, are “so wildly improbable that the chances of its happening, somewhere in the universe, could be as low as one in a billion billion billion in any one year” (p. 283). 
Life on other Planets?
We have recently discovered some new species in the deepest part of the oceans. Some of these have been previously unknown, and guess what? God is still on His throne. He is still sovereign. No human discovery has ever altered the fact of whether God exists  or doesn’t exist. Discovering something cannot make any difference about God’s existence or not, even if life is discovered on another planet. Why would that change anything? If there is life on other planets, then that life had to have an Originator. We still need to be brought to repentance and trust in Christ, in order to be saved, whether there’s life elsewhere or not. Nothing has changed. If there is fossil evidence of life on another planet, God has not moved, and nothing about the story of redemption is changed. So what if there’s life on other planets? The existence of life on other planets doesn’t mean that the Bible isn’t true, or that the creation story is just a myth. God is the Author of life, no matter where it is in the universe (Acts 3:15)!
The Bible and Science
There are dozens of places in the Bible where God’s Word states facts that were unknown by mankind until thousands of years later, meaning the Bible is far more advanced than science was (and probably is!). The earth was not flat as believed, but spherical as God’s Word declared (Isaiah 40:22), the earth didn’t rest on an elephant or on Atlas, but as we know, God “hangs the earth on nothing” (Job 26:7). If the people in the middle ages had read the Bible, they could have avoided millions of deaths, just by following the laws of sanitation that God has laid down thousands of years before. These were intended for Israel’s benefit so that they wouldn’t suffer from the diseases that other nations had (Ex 15:26). If only they had read about quarantining, the Bubonic plague wouldn’t have been so devastating. Thousands of years ago, God’s wisdom stood supreme as He commanded that those who were obviously sick should be isolated from others so that they might not become infected (Deut 23:10-11). These things were thousands of years before their time of discovery, yet science is often so critical of the Bible. They conveniently leave these facts out.
If God purposed to put life on other planets, even so that scientists would discover it and claim, “You see, there is no need for a Creator,” then God would do it. He does only what He pleases and isn’t persuaded by the “wisdom of men,” which is called foolishness (1st Cor 3:19). When has God ever needed the counsel of man, or what could He learn from us? Why would a clay vessel, created by the Potter, ever question the Potter who made them? The vessel sees only the workbench that it was created on….God sees the whole shop and neighborhood. He Who formed us is not pleased when we who are formed question Him and His goodness. Who do we think we are compared to the omnipotent God? God can have life anywhere He wants to have it; in other places in the universe, or only here on earth. It doesn’t matter. God is still God, no matter what we discover!
