i don't know if the following sentence i wrote makes sense and punctuated properlly. please correct me if im wrong. the sentence i wrote is based on the fact that when leaders get power, they try to win time but alwys fail.

hers the sentence:

Thus, we conceptualize that humans have their limitations; time will always be the superior opponent to all mortal human beings.

Thus, we believe that humans have their limitations; time will always be the strongest opponent of all human beings.

"mortal human beings" = repetitive/redundant

I would need to see the entire paragraph into which you want to put this sentence. This sentence alone seems awfully vague.

This is why history repeats itself, pharaohs from Egypt built statue about themselves like Ozymandias, but it never lasts. The American government may be attending it final duration in the near future because of the credit crisis. Thus, we conceptualize that humans have their limitations; time will always be the superior opponent to all mortal human beings.

This is how history repeats itself. Pharaohs in Egypt, such as Ozymandias, built statues of themselves, but these statues don't last forever. In the same way, the American government may be entering its final phase in the near future because of the financial crisis. Humans have their limitations; time will always be the strongest opponent of all human beings.

Compare VERY carefully to catch all the large and small corrections I made.

The sentence you wrote is grammatically correct and punctuation is mostly proper. However, there are a couple of corrections to be made for clarity and style.

Revised sentence: "Thus, we conceptualize that humans have their limitations: time will always be the superior opponent to all mortal beings."

Explanation:

1. "Hers" appears to be a typo, so I have replaced it with "thus" to ensure coherence.

2. Instead of using a semicolon after "limitations," I replaced it with a colon. Colons are commonly used to introduce a list, explanation, or conclusion.

3. I removed "human" from "human beings" since the term "mortal beings" already encompasses humans.

Overall, the revised sentence conveys the idea that time is an insurmountable challenge for all mortal beings in a concise and grammatically correct manner.
