What are these mysterious lights or ships in the sky which normal people claim to have seen?

I do not argue that people have not seen something.  Take these two examples from the Scriptures.  In Genesis 37, the sons of Jacob brought to their father, the coat of Joseph that had blood all over it.  Jacob reached the conclusion based on what his eyes saw, that Joseph had been killed by some wild animal.  His sons, knowing it was a lie, allowed their father to believe false evidence.  A second case is found in Joshua, when the people of Gibeon tricked Israel.  The evidence was men with worn out shoes and old bread.  Israel, without asking God, made agreement with Gibeon.  Their decision was based on false evidence.

When we are taught something as being from God, we go to the Scriptures to verify that what we have been told is accurate (Acts 17:11).  We investigate to find the truth in order that we are not deceived (I John 4:1-6).  This calls upon us to be diligent students of the Bible by studying the Scripture and rightly dividing it (II Timothy 2:15).  This, likewise, enjoins upon us to properly interpret what we read (II Peter 1:20,21).  I do not question that normal people have seen something. 

I have set in movie theaters and seen movies on television that have things happening which just cannot be true.  I understand then that things can appear one way but in reality it is just an illusion or camera trick.  If these lights are “real” and the UFOs are “real” then stop and ask yourself, where are they from?  Is the earth just the “third rock from the sun” or is it “God’s footstool”?  Is man just one creature among millions of other kinds of creatures?  What is wrong with shouting from the rooftops everywhere, the golden text of Scripture.  God so loved the world that He gave His only begotten Son (John 3:16). Are there things I cannot explain in the earth or elsewhere?  Yes, but no mystery can ever over ride what God has revealed.
