The Creator is Missing

I will try to post the video as soon as I can.

As President Obama closed his policy speech on the Middle East from the State Department, he used the words of the Declaration of Independence, stating that people are, "...endowed with certain inalienable Rights...."

He made no mention of the word "Creator."  The line is (emphasis mine, and America's):

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

I've lost count as to how many times he has done this, but there can be no more doubt that it is a simple mistake or omission.  It is a trend. The real question, is why?
