Newbe in need

Hey does anyone know if there is a way to get rid of the default cube? I’m trying to make an eyeball and this cube keeps getting in the way. Also how does one stop the rendering of the cube ( that is, if you only move the cube out of the way)so that you can render your project?
Thanks for reading this.

sometimes those with sight cannot see. thats, I missed that somehow. there is so much to learn it’s mind boggling.

Press Tab Key, Right-Click cube so that entire cube is pink, If it is not, then hit Tab key again, then Right-Click cube until all of it is pink.

Press Delete key. Confirm the deletion. It is now gone.
