Some insights can totally change one’s perspective. One of those insights for me was learning that time had a beginning at the origin of the universe. (Oops, “beginning” implies a point on the time line, so let’s change that to “a point of appearing.”) If time came into existence, then the cause of the universe could not have had a cause, or a history, or a beginning, or a designer, because all of these require that the cause of the universe be located on the time line of the universe, which did not exist prior to the creation of the universe. (Oops, can’t use “prior to” because that implies time.)
Thus, the question of who designed the designer is meaningless when it comes to the origin of the universe. The designer must be “it is that it is,” or if “it” is personal, “I am that I am.”
I realize that this twists one’s brain into a Mobius strip, but it does make sense if you think about it.
