***DISCLAIMER***The following is far from an exhaustive post. Instead, it makes a best effort to sufficiently answer the question.
Recently, someone asked me what I would say to a teenager who believes it is possible for outer space aliens to control us. What follows is the question followed by my response to it.
What would you say to a teenager who thinks it’s a possibility for outer space aliens to control us? And they say that since you cannot disprove that theory, it’s valid until proven wrong.
I would first ask the teenager why he/she would believe such a thing. This helps get to the core of what the teenager really believes about outer space aliens (henceforth referred to as aliens). I would then ask the teenager who makes his/her daily decisions. If the teenager says it is he/she that makes the daily decisions, I would then ask the teenager why he/she thinks aliens might control us all if it is indeed we humans who make our own decisions. If the teenager says aliens make his/her daily decisions, I would ask the teenager to warrant that position with verifiable facts and evidence.
Stating, “since you cannot disprove that theory then it’s valid until proven wrong” is a logical fallacy known as “argumentum ad ignorantiam”, or “appeal to ignorance.” It asserts a proposition is true because it has not yet been proven false or vice versa. However, this theory is easily proven false by personal experience. Not once have I ever had an alien control myself or anyone else I know.
Scripture represents another source that proves the aforementioned theory false. Furthermore, given its authority (2 Timothy 3:16-17; Numbers 23:19; Malachi 3:6; Titus 1:2; John 10:35; Psalm 119:105), it is a much stronger source. Nowhere in Scripture does it state aliens can control people. Instead, Scripture shows how a person is controlled either by a sinful nature (the flesh) or the Holy Spirit. This leaves no room for aliens. Romans 8:1-17 gives good insight on these binary opposites of the flesh and the Holy Spirit.
Therefore there is now no condemnation for those who are in Christ Jesus. 2 For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death. 3 For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh, 4 so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.5 For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit. 6 For the mind set on the flesh is death, but the mind set on the Spirit is life and peace,7 because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, 8 and those who are in the flesh cannot please God.
9 However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him. 10 If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. 11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
12 So then, brethren, we are under obligation, not to the flesh, to live according to the flesh— 13 for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live. 14 For all who are being led by the Spirit of God, these are sons of God. 15 For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!” 16 The Spirit Himself testifies with our spirit that we are children of God, 17 and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.
The apostle Paul makes it clear that there is no condemnation for those in Christ Jesus (verse 1). Paul then differentiates between the law of the Spirit of life and the law of sin and of death (verses 2-4). He also differentiates between being according to the flesh and being according to the Spirit (vv. 5-8). Those who do not have the Spirit of Christ do not belong to Him (verses 9-11). Those who have the Spirit are children of God (vv. 12-17).
Galatians 5:16-24 shows the differences between the desires of the flesh and the desires of the Spirit (NASB):
16 But I say, walk by the Spirit, and you will not carry out the desire of the flesh.17 For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please. 18 But if you are led by the Spirit, you are not under the Law. 19 Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality,20 idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, 21 envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God. 22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law. 24 Now those who belong to Christ Jesus have crucified the flesh with its passions and desires.
In this passage, Paul urges his listeners to walk by the Spirit so they will not carry out the desire of the flesh (v. 16). He also explains how the Spirit and flesh are in opposition to on another (v. 17). If one is led by the Spirit, he/she is not under the Law (v. 18). Paul also compares the deeds of the flesh and the deeds of the Spirit (vv. 19-23). Finally, Paul states that those who belong to Christ (which implies being controlled by the Holy Spirit) have crucified the flesh with its passions and desires (v. 24).
In summary, one can easily prove false the theory that aliens control us. While personal experience serves as a source, Scripture has the higher authority and is thus the strongest refutation against the aforementioned theory. Human beings make all their decisions independent of aliens. Finally, Scripture allows for a person to be controlled by either the Holy Spirit or the flesh. It leaves no room for alien control.
