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

Question

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?

Answer 1

Yes actually it is purely coincidental and AFAIK earth is the only place in the solar system where a perfect solar eclipse is possible
