Activation Lock

you need the apple ID password to unlock it. Find the one you bought the phone from and tell him to unlock it. U can’t do it otherwise

Since this is a second hand phone, Apple cannot remove the activation lock. If the prior owner cannot help you, your only option is to return it for a refund if possible or recycle it and get a phone you can use.

Then you might have to get it to an authorized by apple store to see it and maybe unlock it

But hear me out they might think it’s stollen so they might need the previous user’s personal information and maybe proof that the phone was bought from them

Apple will NEVER remove activation lock on a used phone. NEVER. The phone is useless without the cooperation of the person who enabled this theft deterrent feature.

If it’s stolen then Activation Lock is doing its theft deterrent job. And just owning a stolen device is a crime, even if you didn’t know it was stolen.
