Can we say, "there exist" sounds a little more formal than "there be"?

ChatGPT:
Yes, that's a good observation. "There exist" does tend to sound more formal and precise than "there is/are." The phrase "there exist" is often used in academic or technical writing when discussing the existence or presence of something in a more specific or deliberate manner. On the other hand, "there is/are" is a more common and general way of expressing the existence of something in everyday language. So, if you want to convey a more formal tone or emphasize the existence of something in a particular context, using "there exist" can be a suitable choice.
