Martin P, gosh I'm not sure how I managed this, but it appears I have missed your comment with the wiki link! Apologies for that!!

No worries Abi, it's actually nice to think we have similar thoughts

I made the moon. I was bored one day I just figured it would be interesting to have in the sky. Took a lot of cheese to make.

A Moon in the sky hmmm

Martin P, great minds think alike

I think the cheese theory is fantastic

However if you believe the creators of doctor who which we all should, the moon is an alien egg.

So what might then happen when we start to drill into it in 10 years time. would it crack open and release the alien or would the inside start to ooze out of the hole.
