Impossible to predict. It would depend on what sort of aliens these were, and why they came here. Science Fiction writers have imagined hundreds of possible results from The Twilight Zone's classic horror episode "To Serve Man" (spoiler: "It's a COOKBOOK!") to Isaac Asimov's more humorous story "Buy Jupiter", to the more martial "invasion from space" scenarios like the movie "Independence Day" and the Niven & Pournelle classic SF novel "Footfall".

One thing is certain; it would answer the questions "Are we alone in the universe" and "Is star travel possible" in a very graphic way.

How did Teen Titans form?

The teen titans formed when Starfire came to earth. She was a prisoner and when she came to earth she destroyed some things and she mad sure no one got in her way. Robin, Beast Boy, Cyborg, and Raven fought her and when they stopped Starfire kissed Robin so she could speak English and she flew off. When they found her again she threatened them and then one of the aliens said that if someone found Starfire then they would get an award. Then when the aliens came to earth Robin said that he, Raven, Beast Boy, and Cyborg would protect her, so they all fought all the aliens and when the aliens got defeated and left they became the teen titans.
