It is truly my firm belief that we are all descendants from an ancient alien culture/race that existed long ago. Although the thought/theory has been debated for years ever since "chariot of the Gods", it is now gaining acceptance with scholars and critics alike. The compelling evidence is insurmountable. Ancient ruins that preceded the ability of the cultural to even fathom building, or rather can not even be replicated by engineers to this day! Ancient texts from religions across the world that continually reference beings,spacecrafts,fires from the sky,descended from the sky,unexplainable to them at that time and era but now able to be comprehended by modern man. One striking similarity is the continual appearance of pyramids across continents and civilizations that had no inter connectivity. Why would the Mayans build a pyramid type temple and half a world a way the Egyptians also? It is quite highly possible that Atlantis was one great huge mothership. This motheship,once it shared and bred its offspring and fostered intelligent life on earth ,then began to rise liftoff. Other earthlings,no of the intelligent ancestry, witnessed the rising as a destruction but in actuality it was mere a liftoff. They had never witnessed such power,fire and roar so assumed it was being destroyed. Atlantis existed, and was real. Atlantis was a mothership of an alien intelligent race who gave birth to human offspring of an extra intelligent design. This theory not only explains  existence and destruction of Atlantis, but proves that also we are descendants of ancient aliens, our ancestors.
