How do I do a hard reset on my apple phone without o mowing the ID?

You must have knowledge of the Apple ID to proceed.

Was the Apple ID actually yours:

• Yes. If you forgot your Apple ID - Apple Support
• No. The iPhone is Activation Locked. The original owner must unlock it or it will remain useless forever. How to remove Activation Lock - Apple Support

That iPhone is indistinguishable from a lost or stolen iPhone, that Activation Lock mechanism you;re encountering intended as a theft deterrent, and without that Apple ID and password, or without the original purchase receipt showing the serial number or similar legal paperwork, that iPhone is entirely useless to you. Recycle it.
