I’ve lost safari on my phone. It now goes to Apple

I understand you are unable to find the Safari app on your iPhone. Is that correct? If so find it and drag it back to the Home Screen.

Read Find your apps in App Library on iPhone - Apple Support and refer to Move an app from App Library to the Home Screen.

Sorry, your question is a bit confusing.

Safari is a web browser, it can open any web page including Apple's own website.

If it's opening Apple.com, it means it's working. You can type an address in the address bar at the bottom to go to any other website. Or you can close the tab with Apple's website and open a new one. What exactly are you expecting to see?
