It states that We the People ordained and established it. It belongs to us, the people of the United States and our posterity (the children of We the People). Without it, people can interpret "the people" to mean any people (which is what 14A people are doing re: birthright citizenship).
It wasn't non-citizen residents who created the Constitution, it was We the People (the citizens) of the United States who created it. It was intended to "secure the Blessings of Liberty" to the people who established it, not any person who crossed over the border.
That is what is implied by the Preamble. That is the context that it adds.

The ACLU has some horrible ads during middle-of-the-night TV. They’re showing pics and videos of every diverse critter known to man, and the voice-over says, “’We the people’ means ALL the people.” It doesn’t. It means the citizens of the US.
