The Gutenberg Printing Press is undoubtedly one of the most significant events in world history. This invention, created by Johannes Gutenberg in 1440, was a game-changer that revolutionized the printing industry. Prior to its development, all books were handwritten, and as a result, their production was very expensive. With the introduction of the Gutenberg Printing Press, books could be produced in large volumes, leading to a significant reduction in price, making books more widely accessible. This availability of books enabled people to spread knowledge and information at an unprecedented pace, which greatly impacted religion, literacy, and education. It also encouraged healthy debates and discussions that allowed people to share their opinions and bring forward novel ideas that could change the world. The Printing Press's real value was therefore not just restricted to the commercial world but extended to allowing people an avenue to voice their opinions and raise awareness about various topics. One can truly appreciate the Printing Press's significance when considering the fact that its inventor, Gutenberg, made no profit from it and yet it still remains one of the most important inventions in history.

There are several reasons why the Gutenberg Printing Press could be ranked number one. Firstly, it was capable of mass-producing books and spreading knowledge worldwide, quickly and inexpensively. It saved writers time and consumers money, making books accessible to more people than ever before. Secondly, it was diverse and could print books in different languages, enabling people of different races and backgrounds to read written content. Thirdly, the Printing Press allowed people to read religious texts for themselves, without relying on a priest or other people. Fourthly, the Printing Press sparked the Reformation in religion and played a significant role in changing the world's political order. Lastly, it encouraged creativity and challenging traditional ways of looking at things. These are five compelling reasons why the Printing Press's development is a groundbreaking event in history.

Columbus' Voyage is ranked the second most important event in world history. Although his ambition was to reach Asia, he inadvertently discovered America, which was transformative. As a result, America became a hub for European countries to explore, exploit, colonize, and establish lucrative trade. The voyage of Columbus was a critical step in the evolution of America into what is known today. One of the main reasons his journey stands out is because of the significant exchange of plants and crops from the New World to Europe and vice versa. For instance, plants like tomatoes, potatoes, and tobacco were introduced to Europe, taking root and becoming a crucial source of food and trade. Conversely, horses and other European animals brought tremendous advancements to America. Although there are negative connotations associated with Columbus's journey, like the colonizing aspect, it is still one of the most integral components of world history.

In summation, the Gutenberg Printing Press and Columbus's Voyage are the two most critical events in world history that have shaped the world we live in today. Both events were transformative and brought tremendous benefits to the world in diverse ways. They enabled the spread of knowledge, sparked new ideas and creativity, changed the political order, and more, ensuring that we continue to remember and celebrate these world-changing events today.
