It's not logical because you still haven't demonstrated why it necessarily had to have been designed, and a definition of the designer. You're not backing up your claims with anything.
I never said it had to be designed. I just believe it is, based on my own observations and the observations of others.
Due to this belief I have come to the conclusion that the Universe and everything in it is not eternal, but it's creator is.
If I believed that the universe and everything in it was not designed, then I could come to the conclusion that the creation could be eternal and therefore have no creator.
Comprehend?
