We are too child-like for him to waste his time.
It is very child like to ignore hard truths, maporsche, hard science, hard evidence, when it causes such cognitive dissonance. That's why voting is withheld until age 18.
I expect that all these science deniers are beyond that age.
Impossible means something cannot be true, real, actual. Molten/vaporized WTC steel is a reality, from both WTC 7 and the twin towers. That is impossible according to the USG official story, yet it exists. There is the Meteorite sitting in some 911 museum, a fused element of iron, steel and concrete described by a US reporter as "exposed to temperatures as hot as the inner Earth".
That is 6,000C/10,800F!
The only fuels that alleged hijackers had were jet fuel/office furnishings.
"The temperature of the fire at the WTC was not unusual, and it was most definitely not capable of melting steel.
However, it is highly unlikely that the steel at the WTC experienced temperatures above the 750–800°C range." [max 1,472F]
What is it that makes adults avoid stark realities? I wish I knew.
