The point of the OPs question is whether demons can move physical objects.
I guess when you can't defend your statement that angels have flesh and body, you just ignore them being corrected and proceed to reiterate what has already been said.
But there is no clear exact scripture on the subject, but you assert certainty in your answer.
Then there was a response that said that an angel came down, rolled the stone away from the tomb. But the response was not consistent with the question because the question was not about angels, but demons. However, the rolling of the stone away from the tomb was a one-time event, and there are no other references about angels moving physical objects anywhere in the New Testament.
Again your claims of knowing scripture is lacking. Angels do have the ability to affect the physical world.
Acts 5:19 But during the night an
angel of the Lord
opened the doors of the jail and brought them out. 22 But on arriving at the jail, the officers did not find them there. So they went back and reported, 23 “
We found the jail securely locked, with the guards standing at the doors; but when we opened them, we found no one inside.” 24 On hearing this report, the captain of the temple guard and the chief priests were at a loss, wondering what this might lead to.
Acts 12:7 Suddenly an
angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and
the chains fell off Peter’s wrists.
Acts 12:10 They passed the first and second guards and came to the iron gate leading to the city.
It opened for them by itself, and they went through it. When they had walked the length of one street, suddenly the
angel left him.
Acts 12:23 Immediately, because Herod did not give praise to God, an
angel of the Lord struck him down, and he was eaten by worms and died.
Acts 5:5 When Ananias heard this, he
fell down and died. And great fear seized all who heard what had happened. 10 At that moment she fell down at his feet and died. Then the young men came in and, finding her dead, carried her out and buried her beside her husband.
Lastly the whole concept of guardian angels is the idea that they keep us from harm, often physical harm. Even Satan knows this and tested Jesus with this.
Luke 4:9 The devil led him to Jerusalem and had him stand on the highest point of the temple. “If you are the Son of God,” he said, “throw yourself down from here. 10 For it is written:“‘He will command his angels concerning you to guard you carefully;
11 they will lift you up in their hands, so that you will not strike your foot against a stone.
Many have attested to their guardian angels affecting them in the physical world without them seeing angels. I can personally attest to such an occurrence. But, once, Elisha prayed that his servant could see the angels around them. He describes it so.
2 Kings 6:17 And Elisha prayed, “Open his eyes, Lord, so that he may see.” Then the Lord opened the servant’s eyes, and he looked and saw the hills full of horses and chariots of fire all around Elisha. 18 As the enemy came down toward him, Elisha prayed to the Lord, “Strike this army with blindness.” So he struck them with blindness, as Elisha had asked.
19 Elisha told them, “This is not the road and this is not the city. Follow me, and I will lead you to the man you are looking for.” And he led them to Samaria. 20 After they entered the city, Elisha said, “Lord, open the eyes of these men so they can see.” Then the Lord opened their eyes and they looked, and there they were, inside Samaria.
And, no angel has ever been recorded as possessing a body, because they have bodies of their own. Every appearance of an angel in the Bible has been in their own body and no one elses'. But demons don't have bodies of their own.
Angels have spiritual "bodies". Anyone that has seen an angel as a man does not see them in their heavenly form. Further, often when men see angels, it is only as a vision or dream.
1 Corinthians 15:40 There are also heavenly bodies and there are earthly bodies; but the splendor of the heavenly bodies is one kind, and the splendor of the earthly bodies is another.
I agree with your statement "no angel has ever been recorded as possessing a body" but that does not prove that they have physical bodies. Likewise because scripture says demons can possess people, that this proves it is the only way that demons can affect the physical. I would venture to say that when people do superhuman acts, that is angels doing it not us. So when I fall off the roof of my house, land on my feet with not a scratch, it was my guardian angel affecting the laws of physics such that I did not have a normal fall. And when demon possessed men brake steel chains, it is not the physical power of the one possessed that does such a feat.
Mark 5:2 When Jesus got out of the boat, a man with an impure spirit came from the tombs to meet him. 3 This man lived in the tombs, and no one could bind him anymore, not even with a chain. 4 For he had often been chained hand and foot, but he tore the chains apart and broke the irons on his feet. No one was strong enough to subdue him.
But there is no record that demons can move physical objects.All they can do is to influence a person to move that object.
One correct observation in scripture does not guarantee the truthfulness of one conjecture not stated in scripture.
