Why did astronomers need to change the definition of a planet?

To brainwash mankind in thinking that the evolution theory is the source of creation. Science has revealed much about the universe and our earthly home, and it has brought us advantages in various aspects of life. But there are many questions science has not been able to answer. For instance, astronomers cannot tell us exactly how the universe came into existence or why we are on planet Earth with its abundance of life. But in his own Book, Jehovah answers “Raise your eyes high up and see. Who has created these things? It is the One who is bringing forth the army of them even by number, all of whom he calls even by name.” That “One” is identified as “the Creator of the heavens and the Grand One stretching them out.”—Isaiah 40:26; 42:5
