I am currently reading 'The Threat' by David M.Jacobs, a book that, if true, does not make pleasant reading. If true, Jacobs does provide explanation for abductions, animal mutilations and why the 'aliens' do not land a spaceship on the lawns of The White House and demand to see our leader. Whether fanciful or close to the truth, it is recommended reading for anyone will an open mind.
My problem with 'alien visitations' is not that I cannot accept that life exists in the universe outside of ourselves, or even that 'aliens' move amongst us. It is how they construct the spaceships they travel in.
I once asked the question: Do aliens grow cabbages? In film and fiction aliens are mostly always war-like; a threat to the human race. I wondered if back home, wherever home might be, these same scaly-skinned creatures kept herb gardens and cultivated rare blooms, the same as our red-necked soldiers of war might do.
These days I concern myself with 'who builds their spaceships'? You see, every artist's image of these 'aliens', every characterisation of them in film, has them as weak, spindly creatures, lacking any visible strength. Even if made of lighter materials than we know about ourselves there would be a lot of heavy handling involved in the construction of a spaceship. And if robots did all the heavy work someone or something would have had to construct the robot and someone or something would have needed to make the tools and machines that made the robot that made the spaceship.
Then there is the construction of the hangars - surely the spaceships would need protection from whatever weather there is on the 'aliens' home planet - and the launch facilities required to get the spaceship out of its home orbit.
And then there is the manufacture of clothes, weapons, cutlery etc - they all need factories and labour, and those greys and large greys just do not look, strength-wise, to be up to the job.
David M.Jacobs has already hinted that the 'aliens' who routinely abduct people have no need of food, which kills stone dead the need to grow cabbages. I just hope he can give an answer to how often they need to use a toilet.
