Yes, I see that from the FOX article that you wrote. But you seem to be assuming quite a bit. There is nothing there that indicates that it is thought that they may be from intelligent life.
Worse yet your FOX article starts with a video of a UFO that has been shown to be a natural phenomenon.
One of the reasons that they often have a new batch of UFOs quite often is that the military is constantly updating its equipment and they as a result they are not aware at first of all of the possible bugs in it. Haven't you noticed that the nature of UFO's change as equipment changes? Once explained they are no longer news which is why we do not keep hearing of the same sort of UFO's today as were seen in the 1950's.
Life's ground water went deep inside earths cavities as fresh water when the flood as sea took over the earth.
When water atmosphere mass evaporated ...then fresh water with our bio life earth support microbes existed. Fresh water evaporated too as our ground water heavens is over us now.
Why we have nothing to do with heavens waters historic earth changes. Even today fresh water streams beneath the sea water.
As our living fresh water microbiology gets attacked by overhead heating fallout causes of science....water no longer supports skin health. Or fresh drinking water put into any bodies health.
Seeing trees take in water to grow food...as plants grow by water all bodies change bio health support in its biologies structure. As water becomes unholy changed.
So non supplemented humans biology becomes sick. As we are nature's holy life holy tree water ground balanced.
Science always knew...why they don't release truthful public advice.
