There is ample evidence of the presence of highly advanced beings found in the remnants of many ancient civilizations around the globe. The Great Pyramid on the Giza Plateau in Egypt is a prime example. It is the largest structure ever built on Earth, more perfectly aligned to true north than any building on the planet, it is located in the center of the Earth's land mass, and the curvature of its sides matches the curvature of the globe. It is level to within 1/2 an inch over 13 acres, it's height matches that of all the land mass on Earth, and it was built with perfectly cut stones; some weighing as much as modern locomotive. The ancient civilization that is credited with constructing it did not have the tools, equipment, technology, or the engineering and construction techniques to even clear and level the ground it sits upon. All contractors, architects, and engineers that have studied the Great Pyramid agree that such a feat would be impossible without conquering flight. A race of highly advanced beings that could fly and accomplish such a gargantuan feat, with absolute perfection would probably be considered alien. But this is not the only example of such amazing construction; they exist in thousands all over the globe. A simple way to begin research on this subject is to type the keywords "ancient structures" into any search engine and be prepared to be amazed.
The above plays on the usual deficiencies in human reasoning and penchant for piecing something out of nothing. You can read absolutely anything on the internet and watch almost anything on tv; the world is filled with people with strange ideas. So is there evidence of ancient aliens? No, not anymore than there is evidence for anything else that didn't exist.
The Egyptian pyramids are a commonly used example of these, but it's really no secret. We've found half-built pyramids, we know how they did it. Simple mechanics. Any one who says "all the experts say"... is just trying to gain credibility for their theory: experts absolutely do not agree that, for example, pyramids couldn't be built by humans.
Don't believe everything you read.
There is some evidence that Australian aborigines traded with others from the Asian islands.
None whatsoever.
Some folks believe that aliens have visited, and use this belief to explain the pyramids and other ancient wonders. On the other hand, believing that aliens were responsible for such wonders is - to some people - insulting to the intelligence of ancient people. There does not appear to be any evidence for alien visits that can stand thorough examination.
There has not been any evidence of alien life so I do not know what you are talking about.
There is no evidence of any kind to support the idea.

An ancient pyramid is any of a number of monumental structures built by ancient civilizations in the shape of a pyramid with a rectangular base.
Although Ancient civilizations, like the Sumerians, were able to map our solar system with unbelievable precision, no evidence has been found to support the idea that any ancient civilization, including the Egyptians, used electricity on a large scale, if at all.

No, there is no evidence to support the existence of black magic in pyramids. Pyramids were built by ancient civilizations for various purposes, such as tombs or religious structures, and do not possess any inherent mystical or supernatural powers.
Every civilization it had any effect on.
