Look at the following images, and ask yoursselves why it is that by cross referencing the 'sized images' of the 'sun', the 'moon', and 'the earth', they all apear to be of the exact same size?
If it is the earth casting its shadow on the moon in the first image, it appears almost identical in size and shape as the moon, right? Now, look at the photograoph of the full moon with the sun, the sun appears of a similar size and shape of the moon!
What a remarkable coincidence, thaat despite the sun being so many millions of miles away, and the moon also very far away, that all three planets appear to be of the exact same size and shape!
