The 1st
Angel. The
giant of light discovered in
Antarctica. The information that Adam was confined underground below
NERV HQ turned out to be false -- that underground giant was in fact
Lilith. The real Adam was the
embryo like object brought by
Ryoji Kaji from
Germany. This was result of humans reducing Adam to an embryonic state after waking it up with the
S² theory. The
Second Impact appears to have been an effect of this process. The book of
Genesis in the
Old Testament records that Adam was the
first human to be created by
God in
His image. There are various theories as to the etymology of the word
"Adam", among them: "
earth", "
red" and "
create".
