FRiend, the Lord works His wonders in ways we cannot even begin to fathom. Existence of both extra-terrestrial intelligence AND demonic spirits are more likely the reality. God is capable AND LIKELY to have created both, and I would be going against God in too many ways if I simply wrote off as liars the many people, some of whom I am very closely connected with and who have proven themselves entirely honorable and honest over the decades, who have related IN DETAIL sightings of UFOs that are clearly NOT "natural phemomena" or group hallucinations.
I have never seen one and never want to see one. However, I cannot be so cavalier or so mistrusting as to simply assume so many people are either idiots or liars. I suspect the idiots and liars are at best evenly distributed on both sides of the UFO dispute.
