But that doesnt explain why thousands of us from all around the world, can see it straight above us at say, 10pm one night, then not even in the sky at 10pm the next. Then 7pm the next night, then not again for days even weeks. But all of a sudden its back for a few days around the same part if the sky for a few nights around 9pm directly above us, then no where near that positon 24 hours later. and so on.

I mentioned elliptical orbits because they are inherently unstable.
You may think that most objects in space that orbit something else move in circles, but that isn't the case. Although some objects follow circular orbits, most orbits are shaped more like "stretched out" circles or ovals. Mathematicians and astronomers call this oval shape an ellipse. All of the planets in our Solar System, many satellites, and most moons move along elliptical orbits.
Regarding Lorenzo Lorio's paper contradicting 'moon is in the wrong place based on thier (sic) own observations' I don't see where the paper even addresses this. He's talking about an orbit that has become and is becoming more elliptical than it already was.
If Pluto's orbit is chaotic, then technically the whole Solar System is chaotic, because each planet, even one as small as Pluto, affects the others to some extent through gravitational interactions. But we now realise that although chaos means that some orbits are unpredictable, it does not necessarily mean that planets will collide - chaotic motion can still be bounded. In 1989, Jacques Laskar of the Bureau des Longitudes in Paris published the results of his numerical integration of the Solar System over 200 million years. These were not the full equations of motion, but rather averaged equations along the lines of those used by Laplace. Unlike Laplace, however, Laskar's equations had some 150,000 terms. Laskar's work showed that the Earth's orbit (as well as the orbits of all the inner planets) is chaotic and that an error as small as 15 metres in measuring the position of the Earth today would make it impossible to predict where the Earth would be in its orbit in just over 100 million years' time.
