God deserves the glory because He created us, and the air we breath and food we eat that maintains our lives. He deserves our praise. Humans who are selfish do not deserve the glory because all of their achievements were accomplished with something that they would not have without God.

[God deserves the glory because he made us for his own amusement and punishes us for acting in a manner that he has specifically created us to. But hey, he made us, so... that makes him good? What kind of morality is that? Does an abusive mother deserve eternal praise because she birthed and fed her kids?]

What? He never punishes us for acting the way He created us for, He punishes us for acting sinfully (which because of Adam and Eve's sin is now a part of human nature). And I would say that a mother does not deserve eternal praise because ultimately it was God who created those children.
