When i copied his text to check whether those words are written with the help of Ai or not but results came up with humanize text but meanwhile i also checked above underlined & bold sentence breaking by one sentence into three segments to meet the requirement for ZeroGpt and then the result shows up as below.

In your image, you just took 1 sentence from the post and pasted it 3 times. The sentence itself is obviously NOT AI because AI wouldn't mistake the word "proof" with "prove", which is what its
supposed to be.
As a reminder, please adhere to the following guidelines, which are outlined in the OP:
- post 3 instances of posts by the same user, where
- at least 2 detectors give a result of 70%+ AI
If a user has previously been identified as using AI in this thread, then its OK to include only 1-2 of their posts here.
