Theology would suggest that wouldn't be the case through scripture along the lines of "Man was made in his own image".
But what about the existence of extra-terrestrials? Doesn't that suggest that a higher power saw fit to move the existence of some life
away from the human form. Surely the existence of such beings shows that the mind of God recognises only the two sides of symmetry to be important, with 'no mid-point', hinting that the mind of God could simply be a switch which only sees the two sides of an equation as relevant, as in binary (0 or 1)!
I find your quote interesting though: the significance of the human form is highly relevant with regards to the soul, which I suspect was not created by God, but by a higher power. Therefore we must also suspect that it was not God who is responsible for humanity, but the higher power which is responsible for
all of life.
I, in my humble position, have some questions for such higher powers, with regards to humanity. For example the human form has a number of weaknesses, and I consider it most unfair that I have been created as a human, which is mortal, whereas other beings, such as flora, have simply
forever to contemplate their own existence, which when questioned reveals that they then have forever to contemplate the question further! It seems then that the beloved flora are virtually guaranteed eternal life from their very creation, where humanity is not, and must prove itself first.
