Actually 0.99... is the same as 1. They both represent the same number

If .99....9=1, then 0.999...8=0.999...9, 0.99...7=0.999...8, and so forth to where 0=1?

Huh... Where did you get "0.999... = 0.999...8" from? There's a huge difference here.

Read carefully. I wrote a finite number(0.999...9)

Think carefully

What does 0.99…8 represent to you exactly

If it’s an infinite amount of 9s then it can’t end in an 8 because there’s an infinite amount of 9s by definition so it’s not a real number
