Aliens among us
There are so many conspiracy theories and paranormal foundations based on aliens. I think our current fascination with it has more to do with the media than actual contact, but it's worth looking into all the same.
Calvary Chapel Roswell talks lightly on this issue but profoundly points out that we have several options. Aliens could be paranoia fueled by the media, could be actual creatures from someplace other than our planet, or could be demons.
I think people are looking for a way to explain several points of the unexplainable. For example, there is a surge of scientists who were strong evolutionary (particularly darwinian evolution) supporters turning towards intelligent design. They are not saying that intelligent design supports evolution, but rather the opposite. They state that because of the chasm of explanation and evidence of evolution at a micro-biological level where protein based machines are forming, darwinian evolution fails and intelligent design provides the only possible explanation.
If there is intelligent design, the next important question is where is the intelligence? We used to think that everything in the universe could be formed through matter and energy, but that definition falls short. We are finding evidence in our DNA, the function of the RNA and the process of amino acid structures forming into proteins that there is a third piece to the universe which is information. So with matter, energy and information we are able to explain life. But where does that information come from?
If there are aliens, it's likely they will step forward and make claim for that information - not necessarily because they planted the information but because they can gain quite a bit from doing so. People on earth do this all the time with patents; people claim they invented some process so royalties are due. Imagine some creature coming to earth claiming to have a patent on carbon based life.
My own personal beliefs lead me to believe that the aliens are somehow related to the "watchers" described in the dead sea scrolls and suggested in the Bible. In short, angels or demons that present themselves in some similar manifestation. Throughout the Bible people are able to identify angels apart from humans, so it's reasonable from a Christian perspective.
One pastor mentioned that the aliens we have come in contact with in recent times are more likely demons. His reasoning is that they always focus on the greatness of humanity (where the Bible clearly points out that humanity failed at the point of sin so that we require a savior), and they point out a higher line of thought we should be aspiring to (where the Bible makes it clear that we should be focused on God and pleasing Him rather than reasoning Him).
I have confidence that if aliens do exist - whether as watchers, angels, demons or extra-terrestrial beings - they will reveal themselves more consistently and predominately about a decade from now and humanity will be ready at that time to accept them into the fold.
