I fully understand Your point of view and where You come from Sir, but what I am trying to say is , of course You , me and many other "educated"
people understand the laws of physics which are belived to be true for the moment.
What I mean is , imagine You (pure hypothetical) are involved in a conversation with somebody from the middle ages or even further back , and trying
to explain to him for instance the existance of umm lets say nano bots or cellural phones or something as complex as a airplane.
You would probably be burned alive for herasy or magic or be called a totall looney.
See where I come from ? Scientific theories and kommon knowledge changes drasticly over time , and how manny years has it been from the time people
thought the sun goes arround the earth or that earth is flat ?
Not so long in terms cosmic timeframe . So now try and imagine what science will know and hold for fact in 200 years , 1 thousand years , 1 millin
years .. (if we do not blow ourselves up by that time
)
You , me and everybody else has no idea how such advanced crafts work , how their engines work , what type of material the crafts are made from , etc
.
Of course You can argue that laws of physics are static and that what we know now will not change within the next x years but the truth is we as a
spiecies understand maybe 1% of how the universe works.
So stating something as a fact based just on our todays science knowledge is a rather bad approach imo because in 5, 10, 100,1000,... years people
might be calling us and our theories dumb and uneducated
(For some unknown reasons my english grammar checker is not working so I apologize for all the grammar mistakes , english is not my native language
