For this, more people than you are thankful.
... who happens to be a special creation of God,
There is no evidence for this, and according to my aunt, much against, but I'll take the compliment.

You're working with a definition of "blessed," which is unrecognized by my family. We're both conservatives, so we're on the same side.
Until you find your clone there is at least some evidence you are special. Not a bad start, despite your aunt.
As for the "creation of God," this is what I believe to be true, and why I am obligated to treat you with respect. The fact that my biological being will one day rest in the bosom of the earth will be ample evidence that I have not treated you, nor your family, nor my most bitter enemies, with the respect they deserve.
