There is no doubt that demon spirits may have superior knowledge, even of science and technology.
But look at the following example...
Act 16:16
And it came to pass, as we went to prayer, a certain damsel possessed with a spirit of divination met us, which brought her masters much gain by soothsaying:
Act 16:17
The same followed Paul and us, and cried, saying, These men are the servants of the most high God, which shew unto us the way of salvation.
Act 16:18
And this did she many days. But Paul, being grieved, turned and said to the spirit, I command thee in the name of Jesus Christ to come out of her. And he came out the same hour.
So this demon spirit has superior knowledge when it says "These men are the servants of the most high God, which shew unto us the way of salvation."
But God puts a stop to it speaking out.
Look at the next example...
Luk 8:28
When he saw Jesus, he cried out, and fell down before him, and with a loud voice said, What have I to do with thee, Jesus, thou Son of God most high? I beseech thee, torment me not.
Luk 8:29
(For he had commanded the unclean spirit to come out of the man....
Here again the demon spirit knows more than most people, and proclaims what it knows, namely that "Jesus, thou Son of God most high".
Again it is silenced.
Demonic knowledge is strictly controlled by God.
And anything a demon says, is mixed with lies, or has a hidden agenda.
Let's take another example of demon knowledge...
Gen 3:4
And the serpent said unto the woman, Ye shall not surely die:
Unchecked Copy Box Gen 3:5
For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
In this case, what the Serpent said was true. Adam and Eve did not die in the day they ate the fruit, and they did become as the (demon) gods knowing or experiencing good and evil. To that point in time, they had only known or experience good.
Thus Satan may even tell the "truth" but it was a "technical truth" in that they did not strictly die in the day they ate, but 900 years later.
And being as the demon gods and experiencing good and evil is not what you want.
There are many cases of spirit knowledge, the Kabbalah stakes me as a case in point. But it is so perverted that you never know what is true or false. Therefore God makes it simple. Avoid mediums. That includes seances, ouija boards, people pretending to communicate with the dead, folks who spirit write under the influence of demons, false prophets like Nostradamus etc.
I hate the paranormal so much I refuse to watch paranormal movies. Anything with long Dracula or vampire teeth, haunted houses, twilight zones, villages of the damned, zombies etc.
