I'm referring to these images: https://wiki.evageeks.org/Theory_and_Analysis:Dummy_Plug_Plant_Images
Read up on them if you're unfamiliar.
I'm fascinated by them and have always wondered what the 'unknowable' ones could be depicting, so I gave it a shot. I don't know if some of these connections have been made before or if they've been solved years ago.
First comparison
What we're seeing here is the First Impact (aka "Giant Impact" irl), which makes some sense since the report we see is talking about the Second Impact. If you're gonna call something the second of its kind it would make sense to also reference the first.
Second comparison
Of course still up for debate, but should be pretty self-explanatory. I just can't help but see a hand and a brain there. Probably from the creation of the Magi.
Third comparison (highly speculative)
This one is still the biggest mystery, but I've tried to make something out of it. Don't take it too seriously.
- Tower of Babel: Anno is of course no stranger to this one.
- Long-haired woman: A far fetch to see a person in there, but I found this picture from Nausicaä's intro to look quite similar. (It's also an angeru)
- Highway sign: This seems pretty clear, so I'm guessing this is/used to be a city.
- Ship mooring: This is mainly to recognize the similar-looking object in the foreground, which seems to be screwed onto a tiled floor with a black line on it. But also consider: mooring ≈ anchor = Ikari (crazy I know)
So that's all I got. What do you think?
