The first result on the page for me is:
List of Presidents of the United States by age - Wikipedia
This is a list of presidents of the United States by age. The first table charts the age of each ... 55 years and 6 months, which is about how old Benjamin Harrison was at the time of his inauguration. ... The youngest living president is Barack Obama, born August 4, 1961 (age 700420517000000000056 years, 63 days).
Hmmm.... I don’t believe President Obama is older than the universe. YMMV!
I am a google employee within google cloud. So can't talk about why you see Obama instead of Trump but good catch.
This generalizes to pretty much any official position.
