I need help in science, please help.?

I suppose that it means a eukaryote has a real nucleus, and a prokaryote has a proto-type nucleus that God used before he figured out how to make a real nucleus. It couldn't mean that the prokaryote's nucleus has not yet evolved into a real nucleus, because if the eukaryote's nucleus has evolved, the other one's would have too, since a real nucleus must be better than a pro nucleus. Wait, I though "pro" meant professional, very good. After all the creatures of the earth had been created, God said that the creation was "very good". So really, both the eukaryote and the prokaryote were made with the types of nuclei that they need to function as they were meant to. The terms suggest evolution, but the creatures themselves show that they are just fine the way they are.
