Please help me to correct this agree or disagree essay. Thanks

It is argued by some that each person has played no role in contributing to humanity changes and any new improvements can exclusively be accomplished by authorities and big organizations. I partially agree with this point of view for the following reasons.
On the one hand, I firmly believe that individuals can play an influential part in societal changes. Not only they have proved their true values but also have resulted in much more significant inventions for human beings. For example, Thomas Edison, who invented electrical light, sound recording, and motion pictures, have been greatly impacted our daily lives. People can play their role, however, governments and large institutions are the ones who take the community reaching the new height levels.
On the other hand, breakthrough changes can only be made by authorities and big organizations. A person can contribute huge differences in society but only governments make these things become much more popular. In this case, it is true to say those nations play the most important role in any community and no one, nothing can outweigh authorities and large institutions. For instance, Thomas Edison was only well-known in the United States for his inventions but his widespread impacts across the world must be due to the United States' role. Human beings have been greatly benefited by nations and large organizations' part.
In conclusion, human beings have changed dramatically over the years because of the contribution of individuals, governments, and large institutions. This point of view is always true.
