Greg: When I got to the park, a crowd had already gathered around that weird thing over there.
Steve: Gee! I wonder what it is.
Greg: Beat me! It must have fallen from the sky. Do you have any idea what it might be?
Steve: Whatever it is, it’s man-made. It looks like part of a satellite to me
Greg: Or it might be the remains weather balloon.
Steve: No, it can’t be. I’ve seen weather balloons before, and that’s not the type of equipment they have.
Greg: You see those lights flashing? And there’s a humming sound coming from it. It must be a communication satellite.
Steve: Or maybe one of those UFOs. You never know
