It doesn't melt either.

"The International Space Station orbits the Earth within the middle of the thermosphere, between 330 and 435 kilometres (205 and 270 mi)."
It's understandable that people who haven't left the atmospheric pressure near Earth's surface don't understand the difference between heat and temperature in lower pressures they've never experienced, but if OP works with engineers and PhDs I would hope they would understand the difference and be able to explain it to him. This is NASA's explanation for why the Parker solar probe won't melt even though it will be exposed to temperatures far higher than the melting temperatures of its components.

Your folly, as Neutronflux pointed out, is that heat and temperature are not interchangeable terms.
The Science Behind Why It Won’t Melt
One key to understanding what keeps the spacecraft and its instruments safe, is understanding the concept of heat versus temperature. Counterintuitively, high temperatures do not always translate to actually heating another object.
In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won’t transfer much energy (low heat). Since space is mostly empty, there are very few particles that can transfer energy to the spacecraft.
The corona through which Parker Solar Probe flies, for example, has an extremely high temperature but very low density. Think of the difference between putting your hand in a hot oven versus putting it in a pot of boiling water (don’t try this at home!) — in the oven, your hand can withstand significantly hotter temperatures for longer than in the water where it has to interact with many more particles. Similarly, compared to the visible surface of the Sun, the corona is less dense, so the spacecraft interacts with fewer hot particles and doesn’t receive as much heat.
That means that while Parker Solar Probe will be traveling through a space with temperatures of several million degrees, the surface of the heat shield that faces the Sun will only get heated to about 2,500 degrees Fahrenheit (about 1,400 degrees Celsius).

The one thing i don't understand is how the lunar module does not appear to have created any kind of significant blast creator or kicked up debris when it took off on its return journey to the command module in orbit of the Moon?
Don't misunderstand me through i believe we went to the Moon, and that the answer probably lies in lack of significant atmosphere/properties of the landing area.
Just would like to have it better explained.
I agree but everything I said is easily verifiable, I'm ready.

When you said that he confirmed your findings about "sending a signal from the moon"...what exactly IS on the moon that we are getting a signal from?

Yes the dust does seem to be an issue, then again its one of the reasons we will return, well the abundance of Helium-3 embedded in the upper layer of regolith anyway.
After asking the PhD astrophysicist about the aluminum aloy and sending a signal from the moon, he sadly confirmed my findings

..The exosphere is about 300 miles above the earth and goes out about 6000 miles, temperature of the exosphere ranges 0-1700 degrees Celsius. They would have melted, the space station is 30 miles below the exosphere.
the Van Allen Radiation belts were impossible obstacle.

Leave this part out of the narrative you are creating for yourselves because it stinks of rat

Instruments on the landing module, the late sci fi author Arthur C. Clarke came up with the idea of using satellites long before Sputnik while serving as a CO in WWII, so using triangulation from radio dishes nearly thirty years after wouldn't be a surprise to him.
