When the moon gets between the sun and the earth the Moon which is 1/400 the diameter of the Sun and also 1/400 the distance to the sun blocks sunlight. The size of the moon just happens to be the right size to cast a shadow onto the surface of the Earth. Actually the small differences in the distance from the surface of the earth to the moon make it so that sometimes when the moon is exactly in line with the Sun observers on the Earth can see a ring of sun all around the moon (anannular eclipse) and sometimes the moon is close enough for the shadow to totally block the Sun but just for a small area on Earth at absolute most a few hundred kilometers wide.
