If you decide to read this thread please keep in mind that while I know quite a bit on this topic, I may state facts that are a little off due to my excitement. If this is the case, feel free to correct me. But a majority of what I have to say will one day be proven as fact. What would you say if I stated the pyramids were built, or designed, by aliens, rather than the Egyptians? You may laugh, but I have solid evidence, and there are a growing number like myself who are finally jumping on board and discovering the truth about the past. I won't go into extreme details, although if this topic interests you, a simple 'aliens built pyramids' Google search will give you a number of sites. Basically, let's start with the knowledge required to build such momentous structures. At the time, the Egyptians were not aware of the advanced mathematics we have today. Concepts such as Pi, were not yet discovered. They knew nothing of latitudes and longitudes, nor did they know where the North Pole was, or if it even existed. So then how did they manage to build pyramids that were 1/10th of and inch off being perfectly straight, and how did they manage to construct the Great Pyramid of Giza so that it was perfectly in line with the North Pole? Also, if you take the perimeter of the pyramid and divide it by two times the height, you get a number exactly equivalent to pi (3.14159). Even stranger, the pyramid lies on the point 31 degrees north by 31 degrees west. Coincidentally, these two lines cover the most combined land area in the world, making the Great Pyramid the centre of all land mass of the world. Hmm.(Source) Let's look at the technology around at the time. Supposedly, the Egyptians were able to build the Great Pyramid by lugging stone blocks into position. Each block weighed on average 1.5 tonnes. Apparently, it took them 20 years to complete the pyramid, with 100,000 men working on it each day. But even this large a workforce couldn't have constructed the pyramid with the technology at the time. So how did they manage to get the blocks into positions so extreme that not even a razor blade could fit between two of the stones. Let's look at two of the common assumptions: ramp and roll. The ramp technique states the Egyptians built a ramp that ascended around the pyramid as the structure got taller. This is a ridiculous theory since they would've needed more materials to build the ramp than the actual pyramid. And who was working on the ramp when the pyramid needed full attention? Furthermore, where did the materials for the ramp come from? There was hardly enough stones for the actual pyramid. Also, where did the ramp materials go? We certainly haven't found a large discardment of materials anywhere. The roll technique states the Egyptians cut down trees in nearby regions, and used the trunks to help roll the heavy stones across the ground to the pyramids. Why on earth would they want to do that? While I can't recall the name of the trees supposedly used, they were in fact a food source for the Egyptians, and the number of trees needed for this process would've been phenomenal. For example, how many times could each trunk survive being placed under the stone's weight? Very few. This takes us back to where we started. How did they build the pyramids, in particular, the Great Pyramid? The tools they had at the time couldn't have done the job. In fact, the tools we have today couldn't do the job in 20 years. How did they do it? Simple - they didn't. Before I take this topic outside of Earth, I'll leave you with another striking fact. Throughout their history, the Egyptians made sure to record everything about their civilisation: methods of agriculture, hierarchy, beliefs, events and celebrations, lifestyles. Yet, there is abosulutely no mention of the pyramids being built. Nothing at all. I ask you to find an answer as to why this might be the case? Looking at some of the hieroglyphic depictions created we come across some interesting discoveries. In one picture, a being is depicted and not specified as a god. This is strange, but it is not unique to the Egyptian culture. In fact, there are rock drawings in the Incan Empire depicting human-like creatures wearing space suits. I believe there are similar pictures in Iraq or Afghanistan. So around 10,000 BC these pictures are appearing in Egypt, and then between 1400-1500 AD, they're drawn in the Inca Empire. These are, of course, well before the invention of the space suit. What fascinates me the most are the writings of a tenth planet by the Incans and, I believe, the Egyptians. My main question is this - how did these civilisations even know about the other nine planets (imagine that Pluto is still labelled a planet)? Furthermore, how did they know about a tenth one that only modern astronomy has accepted exists, yet we haven't been able to get an exact location on it. This planet is known as Planet X, and is apparently where the visitors to Earth came from, as stated in the pictures and writings. Trivia: Have you heard about the mysterious fungi that escaped and killed everybody that went near King Kufu's tomb? Was that really a curse, or was it ancient fungi? Maybe, it was fungi from another world? Planet X? Finally, we can all agree the Great Pyramid is something to marvel at. To this day, it has survived exceptionally well. But why, 500 years after the Great Pyramid was built, could the Egyptians fail to create smaller pyramids of equal quality. Today, these smaller clones are crumbling, yet the biggest and the best remains standing tall. But enough fiddling around. If some of you are still skeptical, I believe I can change your opinions. Let's look at the planet Mars. In 1976, NASA's Viking made it to Mars, where it took photographs of some unique objects. In fact, so unique that NASA attempted to cover up the images. But once they were out, it became clear something strange was going on. On the planet Mars, there is an elevated rockface 1 mile long, of a face (see below). At the time, NASA attempted the cover-up that it was a "trick of light". Ridiculous, and disproven when another picture was discovered from the Viking taken at another time and from a separate angle. NASA was silenced. Further research into the structure shows indents for pupils in the eye sockets and teeth in the mouth. Skeptics will argue the recent pictures show it isn't actually a face. While this may seem a worthy argument, I challenge them to answer the mystery of the D&M pyramid. Regardless, the face remains an impressive freak of nature structure. Oh, but that's nothing. Did I forget to mention that just nearby there's a pyramid? Please, view in awe the picture below, depicting the pyramid and face in the Cydonia Complex of Mars. You'll notice that to the left of the pyramid is a possible city. It's a very big coincidence to discover these objects all in close proximity to one another. So, can you honestly deny what you are seeing? But it once again gets better. NASA discovered a second face, on the opposite side of the planet. Similar in appearance to the first, it erupted speculation upon its discovery. But it is with the location of the Cydonia complex that has many people talking. Almost in the equivalent position on Mars as the Pyramids of Giza in Egypt, it's all a little spooky. And finally, the most recent discovery. This one is certainly open for speculation. An alien walking around on Mars? It can't be a rock formation because there's no consistency with the others. Also, it's looks too human-like. In fact, it seems to belong in Star Wars and would be a welcome discovery to Bigfoot fanatics if someone saw it in Oregon. To me, it appears to be running over rocks, looking as we would in the same situation. Well, this took a long time to write, but I'm keen to see what everyone thinks about it. Allow yourself to digest the facts and hopefully you'll become caught up in the mystique of the situation. Aliens exist, there's no doubt, and we've been visited in the past. Perhaps, as could be suggested by the astronaut pictures, we have been visited by our future selves? I'll leave it to you.
