Another reason to wonder how you validate information. The fact that something comes up as the first four links of 2 million hits not an indicator of validity. Instead, it means more people have looked at those articles. They could be looking for any reason - disbelief or belief. 
And that something attracts hits means it is interesting, not necessarily factual. 
For example, after over 60 years, one gets 550,000 hits for "Kennedy" and "assassination" and "conspiracy." That does not make it true.
Plus you never said your search terms. I could tailor my search terms to make it look like Trump was an adopted child and probably find someone making such a claim.
