🗣️ LONG CONVERSATION
Maya: Hey, did you read about the new theory on the lights in the sky?
Leo: Yeah! I think that theory makes sense to me.
Maya: Really? Which part?
Leo: The part where they say it could be a natural event, like lights from gas in the air.
Maya: Hmm, I didn’t think about that. I thought it was a satellite problem.

Title: A Logical Theory
Last week, strange lights appeared in the night sky. Many people shared photos and videos. Some said it was a UFO. Others believed it was a problem with a plane.
Then, a scientist named Dr. Reed gave a theory. She said the lights were caused by natural gases from the Earth. These gases sometimes rise and create lights in the sky when they mix with the atmosphere.
At first, people didn’t believe her. But she showed photos and research. Now, many people say: "That theory makes sense."
