As for Godly perfection. God does not meet an externally set criteria for perfection, he defines it. What He is, is perfect. By definition He can only be Himself, therefore He is perfect.
Perfect is an English word. If you're interested in a real discussion, why don't you quote some real bible text and discuss it?
Since you are imperfect, there's no guarantee you could identify perfection if you saw it. Given that uncertainty, how can you say perfection is impossible? You as an imperfect human, can not perfectly rule out the existence of perfection.
