This is what I summarize it to be but I maybe wrong:
Existence is necessary because there is no possibility of non-existence (argues why - briefly, even trying to deny it you affirm it (argues why))
We and things in universe exists, but aren't necessary existence, since it's possible individually each thing won't exist, while that would negate the premise then non-existence is impossible.
The only existence that can be necessary is absolute existence, in the sense it unites all existing qualities of life and excels all possible levels of it. This specially since all existing beings and possibilities of existence are possible through it. Negating the possibilities are illogical while denying the necessary existence by which things become possible is also illogical.
