UFOs are not aliens.
Just "Unidentified Flying Objects"
Technically, if Shaktiman throws an unknown piece of food from the refrigerator across his porch and into the courtyard it is a UFO.
But an "Extra-Terrestrial Vehicle" - Aye there's the rub.
There is no other "intelligent" life out there. But there is life, vegetal and animal.
"My Father's House has many mansions."
"God", however one may see Him, is not only the Alpha but the Omega, and in the latter State continues the Eternity of Eternities, The Ages unto All Ages
Mathematicians went nuts trying to figure out that "Infinite".
The Former State has no Beginning but what we call a beginning.
This Letters Alpha and Omega are a profound representation.
The Hindus acknowledge the Alpha and Omega IS God as the Lord says "I am the Alpha and the Omega".
These "Infinities" of higher order, if you will led, to a controversial mathematics' proof, highly misunderstood and begun by Georg Cantor's Continuum Hypothesis in Germany in the 19th Century and supposedly proven by Paul Cohen at the University of Chicago & Stanford in the 1960s. I just happened to walk into a post doc research meeting with the Cohen group defining "Omegas" all different types of ways. I was a High School senior, there by chance????????. The research leader, later took me aside and explained the phenomenon. Of course i was awed. I also met Antoni Zygmund while I was a graduate student in the 1970s. Truly their work was very much in tune with Christ and even as jews, I feel they suspected it. They helped me quite a bit.

As to "other beings" how about Angels?
So once again, how we define the "life" properties and how we interpret them can be problematic and to add to that "God" without doubt functions on many strata as thee mathematicians found those many mansions.
