Uncertainty seems to be the only certainty.

Just like in any other issue, you are talking about known laws of physics.

But just think, there are too many unknown laws of physic, and unknown laws of life in general.

To assert anything either way without having full idea or knowledge of the issue is wrong whether it is in assent or in dissent..

For example we can hear only sound having freqeuncy between 20 and 20000 Hz..

Does it mean there are no vibrations above or below..

Even in a regimented and limited field of study like physics, there are more unanswered questions than which are answered, and even among answered issue there is practically nothing that is beyond doubt. Many things which look right at micro level are proved wrong at macro level and vice versa. Uncertainty seems to be the only certainty.

Therefore, claiming veracity or otherwise merely on the basis of known laws of physics, does it make any sense?

I too happen to be a Master degree holder in applied physics.. degree acquired in 1976. But that looks nonsense after 46 years of living afterwards.
