Hi Jay! Yes you can. Your first sentence (She sees something.) is in the present tense while the second sentence (She's seeing something.) is in present continuous. Though there's no grammatical error in these sentences I would suggest you add more to complete the thought: example: She sees something on a table/ She's seeing something on the table that nobody else can. THE PRESENT CONTINUOUS IS USED: - to describe an action that is going on at this moment - to describe an action that is going on during this period of time or a trend - to describe an action or event in the future, which has already been planned or prepared - to describe a temporary event or situation - with "always, forever, constantly", to describe and emphasize a continuing series of repeated actions

Context is important!!! In what context are you trying to use this? What's the situation? /sigh... Context is more important than grammar.

Hi Jay, look for "present continuous" and "present simple". There's plenty of information online about the difference between them. This part of grammar is taught at elementary level.

I heard present verb is also used that I regularly do from past. like, I eat breakfast every morning.

There is nothing different. One is present. The other is present progressive tense, but same in meaning.
