Sorry please ignore the first draft. I just editted a little bit so please read this one instead:
It is eternal, with no beginning or end. It is the creation of everything and will exist after the end of everything. Without it, nothing exists. It is what humans perceive as "time". This four letter word, time, should survive through itself(time) as it is perhaps the most significant word of existence.
Time will forever be the creator of everything. Every movement of creation is linked and fixed to a time frame. Take yourself as an example. You were put to this world through a time process of around nine months. Without time, you would not be here reading my application form, unless magic exists. Since all derivation of actual existence eternally depends on time, the word must be preserved.
Time is also valuable. It waits for no one. The preservation of time could prevent a missed train, a lost race, a death of a loved one...the examples are endless, just like time. A moment not efficiently spent is an eternal loss. This is why humans must preserve time and use it wisely to accomplish goals and to be successful.
Finally, the word, "time" cannot be replaced because time is applied in almost everything, including science, philosophy, and religion. The word is so frequently used and has existed over centuries. Changing this universal word would be changing almost everything, which is such a waste of time.
Time is conquering, precious, and universal, which is why the word must be preserved. After all, no one truly knows the meaning of time.
