Sorry to disappoint you folks, but you’re wasting your time. The citizenship question is not the first in US history.
Subsequent law has dealt with insufficiencies of the constitution on this issue:

Currently, Title 8 of the U.S. Code fills in the gaps left by the Constitution. Section 1401 defines the following as people who are “citizens of the United States at birth:”
-Anyone born inside the United States *
-Any Indian or Eskimo born in the United States, provided being a citizen of the U.S. does not impair the person’s status as a citizen of the tribe
-Any one born outside the United States, both of whose parents are citizens of the U.S., as long as one parent has lived in the U.S.
-Any one born outside the United States, if one parent is a citizen and lived in the U.S. for at least one year and the other parent is a U.S. national
-Any one born in a U.S. possession, if one parent is a citizen and lived in the U.S. for at least one year
-Any one found in the U.S. under the age of five, whose parentage cannot be determined, as long as proof of non-citizenship is not provided by age 21
-Any one born outside the United States, if one parent is an alien and as long as the other parent is a citizen of the U.S. who lived in the U.S. for at least five years (with military and diplomatic service included in this time)
-A final, historical condition: a person born before 5/24/1934 of an alien father and a U.S. citizen mother who has lived in the U.S.
* There is an exception in the law — the person must be “subject to the jurisdiction” of the United States. This would exempt the child of a diplomat, for example, from this provision.
I'll say it again...
Article 1, Clause 4. The Congress shall have Power...To establish an uniform Rule of Naturalization...
Congress can't legislate natural born citizenship.
You look like you don't have even the simplest understanding of the Constitution when you post statements like yours.
You are totally incorrect when you say that natural born is the same thing as citizen at birth.
Natural born does not depend on congressional law at all.
Your research is lacking. The citizenship of the parents is a key issue. This might help:
Minor v. Happersett , 88 U.S. 162 (1875)
The Constitution does not in words say who shall be natural-born citizens. Resort must be had elsewhere to ascertain that. At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners. Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents.
United States v. Wong Kim Ark, 169 U.S. 649 (1898)
At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children, born in a country of parents who were its citizens, became themselves, upon their birth, citizens also. These were natives, or natural-born citizens, as distinguished from aliens or foreigners.
Also the supreme court cases habitually cite “The Law of Nations” Book I, Chapter 19, § 212, which in translation says:
§ 212. Citizens and natives.
The citizens are the members of the civil society: bound to this society by certain duties, and subject to its authority, they equally participate in its advantages. The natives, or natural-born citizens, are those born in the country, of parents who are citizens. As the society cannot exist and perpetuate itself otherwise than by the children of the citizens, those children naturally follow the condition of their fathers, and succeed to all their rights. . . .
