It is not necessary for me to know more than thermite melts steel and is the only thing that could have melted the steel seen falling from the south tower and in the debris pile.
Yes, actually, it is necessary. You would need to know those two things (the second of which, of course, you do not actually know--but, nice try) and much much more, in order to make a convincing case.
For instance, there is every bit as much evidence that high-powered lasers melted the steel as there is that thermite melted it (specifically, none). Do you deny that lasers can melt steel? There is a rich literature on the subject. Certainly, no lasers were found in the pile, but of course that is because the evidence for them was destroyed. So... it is necessary for you to know what the evidence might be that would confirm or deny the presence of thermite, or of lasers. (Come to think of it, lasers can cut horizontally, so lasers are actually a better choice than thermite for your fantasy; have you thought about adopting lasers as your invisible steel-melter of choice?)
For instance, given the utter absence of any physical evidence of thermite or of molten steel, your entire fantasy depends upon the reliability of eyewitness testimony; it is thus necessary for you to know that eyewitness testimony has been thoroughly researched and found to be subject to systematic errors. The paucity of witnesses you are able to pretend support your fantasy, compared to the number of witnesses present during the attack, collapse, and cleanup, should tell you something. That it tells you nothing, tells us quite a bit.
For instance, the color matching you are doing to determine the temperature of your molten steel is dependent on a number of presuppositions. Do you know what they are? For you to make your argument, it is necessary for you to be able to understand the scale and the process behind it. You clearly do not.
You cannot deny this so you will switch to denial #2 "There was no molten steel."
I have no need to do this. To deny something, there must be something there to deny. Your fantasy does not rise to that level.
You are ignorant of a great many important things, among which is the number of things you are ignorant of. You fail, C7.
The fact that you lie so consistently and knowingly argues that you have at least an inkling of how ignorant you are. You know, at least, that you have no case at all, or you would be gathering statements from your "witnesses". You could admit your ignorance... oh, who am I kidding?
