Does the number “infinity exist”

Well there is 2 scenarios that it does and does not exist. Forst scenario that it does not exist. What is the number if we do infinity - 1 would it still be infinity because how would infinity exist, if that 1 subtracted number was something and if infinity was after something what would it be? Also that if i had that the number right before infinity if i get one more of that, would it be infinity or what? Another reason that it is real is that infinity is a number that keeps on going forever and ever and we can not determine. Chance that we have infinite cookies made, like it just keeps coming more and more, but what do you think? i might be dumb

it’s relative

There's measurable infinity and immeasurable infinity

You're not dumb. This is a good thing to be curious about. One can be divided into an infinity. Any unit can be. It's incomprehensible.

like if you draw two dots on a piece of paper there are infinite points in between the first two points. if you make the distance between the points bigger does that make a bigger infinity

Hmmm, mind blown.

Some infinities are smaller than others, for example all the numbers form an infinity but all the even numbers form a smaller one, then prime numbers form an even smaller one and so on but they still are infinities

That said I agree with novel
