The expression "out of thin air" means to create or make something from nothing. It is often used when someone is surprised or impressed by something that seems to have appeared suddenly and unexpectedly, as if it came from nowhere. For example, if someone suddenly came up with a brilliant idea with no warning or previous discussion, you could say they came up with it "out of thin air." Similarly, if something seems to have appeared suddenly without any explanation, you might say it came "out of thin air."
