“Why does the Moon look like it is following us?” is a better beginning than a demand for the right answer. Your child has noticed something that genuinely needs explaining.
Take the observation seriously
You might say, “It really can look that way when we move.” That acknowledges the view without agreeing that the Moon is actually travelling behind the car.
Then give the causal idea in ordinary language: as we move, nearby trees and buildings seem to pass quickly, but our direction toward the very distant Moon changes much less. That makes the Moon seem to follow us; it does not travel along behind the car.
Answer first or ask first?
Choose based on the moment. If your child has a possible idea, invite it: “What do you think?” If they plainly want information, offer the short answer. Questions are useful only when they help someone think.
Keep the follow-up small
An observation on a walk might be enough: compare a nearby tree with a distant hill while you move. Children can point, describe or draw the difference. Do not stage observation from an unsafe road position or while a driver is distracted.
A mistake is not a problem to punish
A child might say, “The Moon is coming with us.” Instead of “That’s wrong,” try, “It looks that way. Let’s think about what would look different if it really were close.”
You can also correct yourself: “I said that badly. Let me try again.”
What if the question is too complicated?
“I do not know all the details” is an acceptable answer. You can check a suitable source later or decide not to pursue it. Curiosity does not require uninterrupted teaching.
A manageable parent habit
At the next interesting question, try three moves: name what was noticed, give one truthful causal sentence and leave room for a follow-up. Stop whenever the child is satisfied.
