Game button won't work

When I press the game button, next to the scene button all I get is a blue screen. Same with the player arrow at the top. I just got this program, and already I'm frustrated because I can't see how it will turn out. Help. Please.

I am pretty sure this means all of your game objects are not within view of the camera, try positioning them closer. To test this go to GameObject > Create Other > Sphere. Then click on it in the Hierarchy, and in the transform component, under position, set all of them to 0, or simply click the cog, and reset.

Hope i have helped, also keep with it, and you will get better!

Oh, you made me so happy. I did the first option and it worked! The second option I don't understand, the cog and reset.

Thanks again. I will stay with it.
