Light, it has been called many things, a particle, a wave, a Photon. One thing is clear, a laser gun has no recoil. Sir Issac Newton proposed a set of "laws" on how physical matter behaves more than three centuries ago and yet these scientists with all their equations, they can't grasp reality.
Reality is, this world is way to beautiful to destroy just cause "we brats" can't grow up and get a grip on what is really going down.
In this whole fight over "black and white", no one has much heard of the "brown". they remain seclusive for many reasons, not the least of which happens to be History.
No Government Official would ever admit the "possibility" of "Aliens". And yet, when confronted with the idea that Central American indigenous were the true "ancients", they fold like a deck of cards. Isn't more likely that 100,000 men carrying 100,000 pounds amounted to only 1 pound or less for each man. Rough bro, with little to no pay, constant snaps of a whip, no dental and little to no strain, no wonder why they needed an anti-gravity lift!
Same thing, only different, but exactly the same, is that not backwards talk, History is full of this. The Sun-dial is older than "The Flintstones", that long ago some "brown skin" had to know the planet was round. "beyond this place, there be dragons", was said to lure away any thought of traveling to the Amerinds. History is said to be written by the Victorious. That means it can't be completely accurate. Our true ancients were molding soft lava rock into tools and statues, that can be called their "iron Age" while the rest of us were in the "Stone Age". "The ones on the long boats are from a far"and they were said to have mystic vision. Their Mathematical skills were unmatched as well and pretty much still is.
Further more, it is been proven time and time again that the less advanced is swamped or destroyed by the more advanced. If by chance they were benevolent enough to not kill us, they would have considered not even messing with us. It is way more likely that "brown skins" and their marvelous craftsmanship, along with their almost immortal workmanship and distant origins earned them the term "alien"
