eli5: How come the moon and the sun appear to be the same size more or less to us from Earth?

This may seem like a stupid question, but how come during solar eclipses the moon happens to be an almost perfect for over the sun? Especially considering the fact that they are so different in size and distance from the Earth? Is this coincidental?

The other answers are right, but they should mention the SPECTACULAR coincidence.

The moon is 400x smaller diameter, but also 400x closer to us. The fact that it’s the same factor is a complete coincidence, but that’s why the sizes match so closely. The moon is smaller but closer…**by the same amount.**
