The Sun happens to be 400 times the Moon's diameter, and 400 times as far away. That coincidence means the Sun and Moon appear to be the same size when viewed from Earth. A total solar eclipse, in which the Moon is between the Earth and Sun, blocks the bright light from the Sun's photosphere, allowing us to see the faint glow from the corona, the Sun's outer atmosphere.



No other moon in the solar system can cause a solar eclipse if you were to view it of an other planet e.g. mars



The chances of the moon appearing the exact same size are extremely small.



This does give some credibility to the moon been moved into place next to our planet to help induce life on it.



The moon has to have been in place a lot longer than 6000 years but I do think there is a possibility It was placed there. The moon has to have been in the sky at least a couple of 100000 years though.



I believe there is evidence that the moon is actually older than the earth as well but I will have to go digging the internet to confirm that.



And lets not forget that a lot of scientists think the moon might be hollow aswel.
