Hello zpzn,
Ah ... the moon! So beautiful - and essential to our seasons and therefore life on Earth! But where she came from ... that is really still truly a mystery! the Chinese believed some of their gods (perhaps aliens?) lived there. The Chinese actually just recently returned to the moon for unknown scientific test whose results nor purpose have been shared! NASA too has made numerous secret missions to the Moon since Apollo 12. Very interestingly the Moon and the Earth have both been obscured to ring like a bell when struck! This is completely at odds with the standard thinking on what is inside our planet. It was thought it was a liquid molten core - but that cannot be the case - the hunt for cosmic truth continues!

Upvoted and resteemed :D
