What am I? (ft. cool poems)

Question

Without me,
There would be no vowel.
Though consonants would exist,
The alphabet thrown in the bowel.
But, now, another problem occurs,
For bowels exist not,
When, Death, I am yours.

But, worry not,
For without me there is no person.
And surely, nobody would be foolish enough,
To remove themselves from their thought.

^{What am I?}

Answer 1

Going off Rubio, are you

the letter E?

Without me,
There would be no vowel.

vowel needs an E

Though consonants would exist,

the letter E is not in the word "consonants"

The alphabet thrown in the bowel.

The alphabet wouldn't be complete without the E.

But, now, another problem occurs,
For bowels exist not,
When, Death, I am yours.

bowels has the letter E, and Death does too.

But, worry not,
For without me there is no person.

person also needs an E.

And surely, nobody would be foolish enough,
To remove themselves from their thought.

maybe people wouldn't be foolish enough to remove "themselves" from "their thought" because there isn't a string of "themselves" in it?

I don't know what the title means though

Answer 2

You are

the letter O.

Without me,
There would be no vowel.

vowel needs an O.

Though consonants would exist,

O is not a consonant, so they're not affected

The alphabet thrown in the bowel.

The alphabet wouldn't be complete without the O.

But, now, another problem occurs,
For bowels exist not,
When, Death, I am yours.

bowels also need an O.

But, worry not,
For without me there is no person.

person also needs an O.

And surely, nobody would be foolish enough,
To remove me from their thought.

thought also needs an O.

Also,

every line in this poem contains at least one O.
Cool poems need Os, and this one wouldn't exist without them.
