No, you didn’t say “it looked almost as big”. What you said was “Almost looks like a nuclear explosion.” You said nothing about big or not big. Why you need to lie about what you said, I’m not going to get into.
I once knew a guy who would say something wrong in front of ten people, and when his words were repeated back, would immediately claim he said something different. Whether you’re doing that I don’t know or care. Anyone reading these posts know what you “said”.
The primary visual attribute of a nuclear explosion, that is, the characteristic that makes it “look like” a nuclear explosion, is a mushroom cloud. There are non-nuclear explosions that “look like” nuclear explosions because they have the characteristic mushroom cloud. The Aug. 4 2020 Beirut explosion being a well known recent one.
The one in the video did not. In fact it was obvious from the video that the material which was blowing up was spread in a line, NOT a point source.
THAT is what I MEANT, and it seemed obvious enough to me that I did not bother to explain it. I do not write for morons.
