can i legally make a facebook page for my business without having a business license?

[Bob Smith]

Sure can - it's considered free speech. But don't start accepting customers, because then it becomes another issue.

EDIT: I think people can place orders, but you can't accept money from them. Make sure to file your papers with the appropriate authorities before accepting cash.

Advertising is completely fine. There is no exchange of goods and/or services.

The exchange is implied, but so are other things. I'm just giving you information I learned from my accounting law class. No answer on here will ever replace a call to your local district attorney's office, so for further information, I suggest contacting it.
