4 year old insight

Last night, we had an earthquake at about 4:30 a.m. It was several miles away, but the effects were felt for miles. Husband and I woke up to the bed shaking and the windows rattling in this old house. It only lasted about 1 minute, but when you are wondering WTF is going on, it seems like forever. Jacob was the only one of the kids who woke up, and he was screaming. I go in there to comfort him and he says "Someone was shaking my bed". I explain that it was an earthquake. I didn't have a good explanation to what caused the earthquake, but that was okay, because he did. His answer? "One of the spaceships in space didn't watch where they were going and they ran right into Earth. That's why we had an earthquake". And he was quite serious. I just wonder where he comes up with these things!
