"add into the equation the ability to go faster than the speed of light to travel to other solar systems thousands of light years away".
Not exactly, it was actually proven(almost a hundred years ago) that motion is not even necessary for traveling a given distance(time is relative and velocity=distance/time). It has also experimentally been proven that the entire universe exists in many different places at the same time;wave-particle duality is an example. Are these things that you understand?
Besides, regardless of whether or not extraterrestrials are visiting earth. You are not going to explain how hunter gatherers were transporting and cutting diorite stones weighing 131 metric tons. Evidence suggests contrary to your beliefs!
Some of the stones used at baalbeck were around 1000 tons. These stones are impossible to move now! Never mind that though, once these stones were quarried, dressed and transported sometimes 100s of miles and often hauled up mountains and across bodies of water, the knowledge of the solar system was needed to align these monuments to the stars creating in affect calenders that would predict celestial motion for thousands of years to come. All of this by stone age man? i think not.
1000 tones is about 1/3 of this cranes lifting power. It would take a hundred(my bad,actually ten, lol..close enough) land based cranes to move 1000 tons....wrong image,but, whatever


If I can't explain something than I always blame the Aliens too.
