The phrase “hardest query on the earth” refers to a query that’s extraordinarily troublesome to reply, usually on account of its complexity, ambiguity, or lack of a transparent answer.
The idea of the toughest query on the earth has been explored by philosophers, scientists, and intellectuals all through historical past. Some consider that the toughest query on the earth is one that can not be answered, whereas others consider that it’s a query that has but to be requested.
