Could you proofread these explanation please?

Hi teachers,
Could you proofread or reword these explanations please?

The simple past is used to narrate past habits, facts, preferences, and schedules. It expresses completed actions at a definite time in the past. In other words, we use the simple past to narrate the principal events of the story.

Which one is better between the following options?
a) The simple present is also used to narrate habits, facts, preferences, and schedules. We use this tense to make the story more interesting, more emphatic, and more vivid.
b) The simple present is also used to narrate habits, facts, preferences, and schedules from the past. We use this tense to make the story more interesting, more emphatic, and more vivid.

Thanks in advance
