I have a guess as to how the alien got to Earth. Just a guess, so bear with me.

This concept art from Guardians of the Galaxy shows an alien spaceship hovering over what looks like a human child. It's been said that Peter Quill was abducted into space when he was a kid, so I'm assuming that the ship is Kree. While they were taking Quill, a skirmish may have ensued that resulted in one of the Kree dying and being left behind so the humans could find him.
