Why not? Grammar and language do not stand on their own. They have being as the support and the expression of the Being is "I am".
Of course they do; this becomes obvious when you look at the languages of things that don't have "I am."
Without "I am", the universe is indeterminate.
The universe is indeterminate anyway, so "I am" doesn't improve anything.
Without "I am", the 17 objects that you talk about will be meaningless.
I could, if you absolutely insisted, go through and define the entirety of mathematics, from arithmetic through to field theory, without using the phrase "I" once. There is no observer in mathematical reasoning, and so nothing to say, "I".
What are those seventeen and how they are known? Are then known in absence of given power of awareness? Are these seventeen the funadamental ones?
The 17 are: the up, down, top, bottom, strange and charm quarks, the electron, muon and tau particles, (and corresponding neutrinos) and the force carriers: the photon, gluon, and W and Z bosons. There's also the graviton/Higgs mechanism, which hasn't been verified to exist, but probably does. They are known because they are part of a mathematical construction that has yielded correct answers to all current experiments.
Incidentally, They can be known by entities that do not make the connection about what an "I" is.
