A spirit-Being in its free state has almost unlimited power. A spirit-Being does not feel pain, and therefore cannot be punished or sent to bed without its supper when it misbehaves.
The reason humans were created is to serve as individual prison cells for spirit-Beings in this prison-planet reform school. That way, through the human, the spirit-Being can be corrected when it does wrong, and rewarded when it learns its lessons and passes its tests. We are to learn to overcome and control all of the selfish tendencies of the human, so we are doing our Creator's Will for the greater good in eternal time, rather than continuing to serve the selfish interests of a mortal human.
Think about it.
Materialism, greed, envy, resentment and the fear that drives them all are
ALL self-centered human emotions, which are completely and
totally illogical. Humans live their entire lives trying to acquire as much material wealth as possible, while acknowledging that we can't take it with us. This selfish, materialistic mindset is literally destroying this planet, which is the life-support system for
ALL plant and animal life, including the humans.
We have been warned by our Creator - through His Firstborn Son known here on Earth as The Messiah/Christ - that it is
IMPOSSIBLE to serve Him and materialism, because they are polar opposites. Our Creator's Law requires all of us to treat our neighbors with the love and respect with which we would like to be treated, and to take care of our natural surroundings, learning to waste as little as possible by conserving everything.
Of course materialism is the exact opposite, wasting as much as possible for selfish gain, which eventually destroys
everything. There's an old Cree Indian saying which sums up this situation (our present course) well:-
When all of the trees are cut down;
When all of the rivers and lakes are polluted;
When all of the fish have been caught from the sea;
Only then will you realize that money cannot be eaten
THAT is why we
MUST learn to control these human animal bodies, remember who and what we
REALLY are, and return to keeping our Creator's Perfect Law.
With this
TRUTH and
LOGIC in mind, what purpose would it serve for someone to be placed inside the body of something other than a human? An animal can only learn how to do what it's programmed to do: survive. A human+Being on the other hand, can learn to be selfless.
Perhaps the car and driver analogy at the linked article below will be helpful.
Are you the car or the driver?

Truth doesn't care about what direction it comes from, or what doctrine it adheres to, or who accepts it or rejects it. And it doesn't need anyone to defend it, either.
The Truth is we have all had thousands of Earth years to learn our lessons, beginning with we do
NOT know better than our Creator. Some will learn these lessons and make themselves spiritually fit (ever strengthening in faith) and survive; others won't.
