Oops, you seem to have parked (crashed) right on Granny's mansion!
You being an alien of considerable acting talent, a plan quickly forms in your mind.
It's easy: All you have to do, is get Granny to bed before she realizes that her house is gone and her family is dead (on her birthday).
As soon as she's gone to sleep you can fix your ship and leave earth again.
Can you act your way out of this little mishap?
