Do your own research. It really is not that hard. Put in ‘original intent’ of the Constitutional phrase ‘natural born’...
Now there are a bevy of people all across this nation on both sides of the political spectrum that do not care for that requirement ‘natural born’, but thus far you are not going to find ‘case law’ or acts of Congress that has touched it... Cruz knows darn well he does not fit the ‘original intent’ of ‘natural born’.
As a nation of laws, the content of google is not authoritative. It can be a useful tool to help find something authoritative, but as you readily admitted, there isn’t much to go on.
If you believe that congress can not define what is not present in the constitution, then you cannot believe in the rule of law. The only other options is really rule by justice since there are many documents and the answer can depend on which document is cherry picked.
I reject your premise, and absence an agreement on that... there is not ground to debate on. We simply disagree.
