Even all the things that Jesus did have not been disclosed. As John told us (21:25): Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written. It is always interesting how backward-looking men shrink God to justify their narrow thinking.
We can speculate all day about things. But going back to "need to know" I believe God gives us all we need to know while humanity still exists. It's a waste of time and energy and frankly a distraction from God to invest so much time energy and hope in aliens of which there is no evidence in the bible or in science.
You haven't been paying attention.
Something is here... NOW.
Is it alien? Is it demonic?
No one knows.
But that's the subject of this thread. That's why former military and intel community men and women are testifying before classified Congression hearings IN DROVES.
Use your God-given mind...or rush to Sunday School where you can pretend to live in the past.
OR WAKE UP.
I don't mean to pick on your, but your comments are thought-provoking.;-)
Science is definitely involved in trying to understand what we are dealing with in the UFO matter. I refer you to Garry Nolan (Nobel nominee in immunology) of Stanford Medical School. Many top scientists (physicists, metallurgists, mathematicians, immunologists...even theologians) are involved in this matter but they don't advertise it because of the stigma the military has built around it (to keep it hidden).
If you aren't aware of the current environment regarding UFO/UAPs, you aren't aware that it has changed over the last 25 years.
