Hello ~ That is the activation lock. If the person/persons that you bought the iPhone from cannot or will not remove it …the iPhone is basically useless to you. If they cannot/will not remove it…return it and get your money back. We cannot help remove it nor can Apple. Take a look here:

How to remove Activation Lock

That’s not possible.

No one has that information.

Apple values your privacy and has safeguards in place to ensure that no one can access the device.

You will need to reach out to the owner because it is the owner’s responsibility to properly erase the device before selling it.

Until then, it is locked. 🔐
