Because satan can’t be omnipresent like The Most High, he is up to his cheap tricks using his tech to try and mimic the best he can.
His time IS short!
Isaiah 14:12-14:
How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:
I will ascend above the heights of the clouds; I will be like the most High.

Revelation 20:10
And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
[And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.]
And the interesting thing about that verse is that it tells us that the Antichrist and the False Prophet are in the Lake of Fire ALONE for 1,000 years before even the Devil himself joins them.
