Simply put , Jehovah tolerated Satan coming and going before him in the heavenly realm for six thousand years before having him cast out of heaven .
Think about that, six thousand years .! and having conversations Jehovah and Satan .No shunning of him in all this time .6000 years. We have an example of that in the book of Job.and elsewhere.
The same is true with Jesus Christ ,according to the Jehovah`s Witnesses he was the first born of all creation and he also obviously tolerated Satan for six thousand years .Their is no example of shunning their either .
Jesus was tempted by Satan for fourty days { why was he with him for fourty days anyway ? } as well as going up in a mountain with Satan willingly so Satan could tempt him again , what was wrong with this person ? Was he a glutton for punishment ?
But despite all of the foregoing and Jesus in all that time not shunning Satan it took him another two thousand years to oust Satan from heaven {so for six thousand years Jehovah and Jesus tolerated Satan coming and going in the heavenly realm } and where did he oust him to ? Earth , thanks Jesus that was a real loving thing to do ,you could have put him anywhere in the Universe on any uninhabited planet , but no you chose to put him down here on earth to mess with us yet again.
That he was already doing so for the past six thousand years anyway ? Go figure ?
