The original meaning of this sentence is the principle of leverage. As long as you have the right tools and a suitable fulcrum, you can easily move the earth (a mass object similar to the earth) by using the lever principle. This sentence was said by Archimedes.

Lever principle: A system that satisfies the following three points is basically a lever: fulcrum, force point and force point. The lever principle is also called "lever balance condition": in order to balance the lever, the two moments acting on the lever must be equal. Namely: power× power arm = resistance× resistance arm, which can be expressed as:

(F 1 stands for power, l 1 stands for power arm, F2 stands for resistance, and l2 stands for resistance arm).

Archimedes (287 BC-2 BC12), a great philosopher, encyclopedic scientist, mathematician, physicist and mechanic in ancient Greece, was the founder of statics and hydrostatics and enjoyed the reputation of "the father of mechanics". Archimedes, Gauss and Newton are listed as the three greatest mathematicians in the world. Archimedes once said, "Give me a fulcrum and I can pry up the whole earth."

Archimedes also put forward the lever principle in the book The Balance of Plane Figures. He first regarded some empirical knowledge in the practical application of leverage as "self-evident axioms", and then proceeded from these axioms, applied geometry, and obtained the principle of leverage through strict logical argumentation.
