"5. The melting Point of Steel is 3000F and Fire is around 500-700F with burning Jet fuel around 1200-1400F"

And here is where all this BS goes wrong. The steel doesn't NEED to melt---it just has to be WEAKENED to the point that it can no longer support the already-existing stresses of the weight of the building it supported. The WEAKENING of steel occurs at a point FAR below the melting point. Add to that, that the stress load has just been INCREASED over its design limit by a reduction in the number of support elements BROKEN by the impact of the airliner.

Shame on Steve Jones for getting involved in this ****.

Exactly. These people have never heard of the concept of annealing, or softening a metal to allow it to be worked. In fact, it's well known that depending on the type of steel you're dealing with, the anealing temperature occurs at between 1300 and 1500 degrees, and requires extremely slow cooling, over a number of hours or even days. But even if the steel weren't properly annealed, simply heating it to those temperatures and allowing it to cool naturally would weaken the structural steel dramatically. Anyone who ever took a metal shop class in highschool should know this stuff!
