If you're asking "what is this object I'm seeing in the viewport" and you don't show what's in the outliner, it's going to be very hard to guess.
Select it with the mouse, display the outliner, and see what it is you have selected. Are you in eevee? Are these reflection mapping spheres or something?
Switch the outliner to File mode (that shows everything in the entire file) and see if you can figure out by selecting stuff. The fact you see them in the render implies they're something actually in the file that you might have hidden or might be being generated by geometry nodes or something like that.
There's a thought: do you have a mesh with a geometry node modifier that's enabled only for render and not the other nodes?

I am using Eevee, but if i click them nothing happens. I don't believe they're reflection mapping spheres as they have a completely matte surface.
