This appears to be a quite ludicrous statement. How could we know the Moon is not a natural planet? The answer is that we know because it is too big, yet too light in mass; it is in the strangest position imaginable relative to the Sun and the Earth and it behaves in the most incredible way every month. What is more, it carries a whole series of quite specific messages that tell us it is an 'engineered' object.
It's an odds on certainty (for a whole host of reasons) that if it were not for the Moon I could not be writing these words or you reading them - simply because none of us would be here.
The Moon is as old as the Earth and it has definitely been orbiting the Earth almost right from the start, so it can't be a captured asteroid but although it's made of the same 'stuff' as the Earth, it only contains carefully selected bits of that stuff.
The Moon's surface is covered with gravitational anomalies that can't be easily explained and it could well be hollow at the centre (which all scientists who know about these things say should be impossible.)
The Moon is a deliberately created scale model of the Sun and it presently stands at a distance from the Sun and from the Earth which is totally outrageous in terms of the mathematical and physical results.
In fact there is very little about the Moon that isn't odd and which doesn't seem wrong for something that came into existence by chance.
I don't expect you to believe what I say just because I am saying it. I want to prove to you that the Moon was deliberately and extremely carefully engineered to do a host of jobs for the Earth.
A lot of the proofs are mathematically based. Some of you will want to see the figures and test them yourselves. Unfortunately there isn't room in this website to show all the mathematical proofs. To see those you will have to get our book 'Who Built the Moon' from the library (or better still buy it!)
But I can explain the outline facts so let's begin at the beginning. What is a Moon and why is ours different from all the other moons we know about?
