Hathor was the Egyptian goddess of the sky back between 2686–2181 BC -

But some people - like Graham Hancock - believe that Hathor was a recent corruption of some far more ancient knowledge. They think that there was a great global cataclysm back somewhere around 10,000 to 14,000 years ago, that almost completely wiped out races of people on Earth, who had knowledge far superior to ours. Some of that knowledge filtered down in the form of the Egyptian gods and the gods of the other ancient nations of the world. See

According to this understanding, the Temple of Hathor at Dendera, Egypt, was simply built to honor a goddess, the real knowledge of whom had long since passed away. This goddess always retained some great amount of honor, even when other gods and goddesses seemed to become popular. The question is, why? The answer can be seen in her greatest temple.
When you visit the Temple of Hathor at Dendera, you will see the sky... the sky adorning the ceiling of the Temple. The constellations are up their, in clear and accurate view, lasting from ancient times. But what is really exciting is the columns holding up the sky (roof). Note in the picture below, the columns with their "scripting" on the sides, and the capitals on top. Look at the capitals in the picture, below. Notice that they are 4-sided, with each side being a carving of the face of a man (a pharaoh?) wearing ancient Egyptian headdress.
Of course, the carving of the capitals was done with the best information that the sculptors had at the time. But everybody should be familiar with the headdress form on the top of these pillars that are holding up the sky. Take a close look at them. They are the base of rocket engines.
The ancients had mastered the method of placing their rocket engines atop of their rockets. This is shown by the pillars. And the fact that the pillars are pointed at the sky shows that the ancients could fly to the lands of outer space. We might make it to Mars. But if we find life there, it came from here... from the ancient people who had knowledge vastly superior to ours.
