Expanding on what mysticfive has mentioned, くれる indicates an inward giving. So for example, someone outside your company (lets say, Mr. Yamada) sends a present to someone in your company:

「山田さんは同僚にプレゼントをくれました。」
Mr.Yamada (a person outside the company) gave my coworker a present.

Likewise, if an alien gave someone on earth something, we could also use くれる. The aliens being the "outsiders" and humans being the "insiders."

That is, unless you associate yourself more closely with aliens...
