Yes, green men from outer space are among us. The thing is, they are invisible (and more than likely fictional too.) They have amphibian ancestors. They have sucker tips on their fingers and toes. And they can disintegrate you with their ray guns.
Of course you can learn more about these aliens and the amusing threat they are trying to pose in the novel Catch a Falling Star. Of course, of course, the greedy publisher of that book still has it insanely over-priced. You would be better served by getting a free copy of the sequel Stardusters and Space Lizards, available now in Kindle e-book form for free from September 24, TODAY, until midnight September 28.
There are many things that make the fin-headed, amphibianoid Tellerons dangerous. Their dangerous technology includes the highly lethal Skortch Ray which disintegrates the target, dissolving sub-atomic bonds between molecules and turning people, things, and insane attack-poodles into piles of molecular dust. They also have personal cloaking devices that allow them to move around our planet invisibly.
But the most volatile and dangerous factor about these space men is that their species, heedless for centuries of the dangers of inbreeding, are now almost totally incompetent.
Being incompetent and totally failing to invade and conquer a small town in Iowa, let alone the rest of the planet, they flee back towards possible safety at a potential home-world. But, being incompetent, they accidentally end up at the planetary system of the Galtorrian Space Lizards, a highly treacherous race of cannibalistic saurian humanoids. And even worse, they find themselves in a situation where they either have to successfully invade and conquer a world far ,more dangerous than Earth or resign themselves to being nothing more than space-lizard food.
Although the Tellerons could not conquer the Earth, they did benefit from their visit there. They learned another way of life from Earther television programs. They learned to love music and dancing. They even learned that children are useful for other things besides being a supplemental food supply.
Now, you may think that invisible Tellerons infiltrating our society is not as big a problem as I am saying it is… well, based on what I have told you, that is probably true, They are more clownish than even we are.,, except for Boris Johnson. But Telleron-invasion awareness is important never-the-less.
