An apple fell on his head and wonder why it was pulled to earth
Gravity is the major force in the Universe controlling matter. Gravity controls the structure of the Universe.
In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. He also demonstrated the generalised binomial theorem, developed the so-called "Newton's method" for approximating the zeroes of a function. He used the methods of calculus to solve the problem of planetary motion.
Isaac Newton
he proved that there was a force called gravity. the moon's gravity causes water to rise.
Newton
Gravity wasn't invented. It is a force of nature and has always existed. As for its discovery it was known to the early humans that things tend to fall down. As for theories of gravity the first big milestone was Newtonian gravity created by Isaac Newton in 1687. The second, and the most accurate one known today, is called general relativity and was published by Albert Einstein in 1915.

The force is the Newton unit in SI. For gravity the force is the weight of the object in Newtons
Newton was the first to propose that there was a force of attraction between matter. He called this force gravity somewhat to counter Aristotle's explanation that things rose because of "levity". Newton said things fell because of gravity.

The world worked before Newton. Affter Newton's Law of Gravity, we understand better why and this allows us to avoid problems and create new solutions to problems.
