Is this paragraph correct with the Capitalization and punctuation marks

Question

Valentine’s Day is celebrated on February 14, as a romantic festival. People send their sweethearts greeting cards that say “won’t you be my valentine”, Children like to make their cards from paper doilies, red construction paper, bright foils and samples of wallpaper. All of these customs probably have their origin in the ancient Roman festival of Lupercalia, which took place every winter. The festival honored Juno the goddess of women and marriage and pan the God nature. According to the popular book antiquities that was written in 1877, England began observing this Holiday as early as 1446. In the United States, the holiday became popular after the civil war. Admirers today continue to send their sweethearts cards, chocolates, and flowers.

Answer 1

You still have more mistakes than I can tell you about after "The festival honored..." We've been over this before, several times. I ask you, are proper names capitalized or not? What do you do with the title of a book? Is "civil war" a proper noun, as the NAME of a war? Are NAMES proper nouns? Do you use a capital letter in your own name? THINK.

Answer 2

Also, sentences are NEVER ended with a comma, as you do several times here.

Answer 3
