The solar flash would be a micronova. I think it would cause a pole shift.
There have been times before the moon. There will be times after the moon. We already destroyed one planet in this solar system. It's known now as the asteroid belt. They tracked back some of the asteroids, which come together at some point in time, in the past, as a planet. Ergo, they know exactly when this happened. The Bible refers to it as 'The War in Heaven'. There is some remote viewing data about that event. Generally, remote viewing data has proven to be incredibly accurate. It was a war between Mars and Tiamat, a.k.a. Maldek. One side of Mars is covered in craters, and there are more clues that suggest this story to be true. The story goes that survivors came to Earth, in the moon, which would be a spaceship. It certainly came from somewhere. It hasn't always been there.

Aside of all that, I don't think most skin cancer is caused by the sun, but rather by the toxic ingredients of sunscreen, which are all absorbed by the skin. All of 'health care' is corrupted. The Rosenau experiment, in 1919, showed that viruses do not even exist, contagion is a myth, and therefore, vaccines are made for the sole purpose to poison us, so we eat more of their pills. A patient that gets cured is a customer lost.
