Here's a Crazy Question- New GUI

I built an HUD for a new space shooter game. It has fire buttons to shoot two type of weapons, radar, throttle, and shields. I found a great prefab to use as a space background, asteroids and other cool objects to use. The only problem is I can’t see any of them. Even when I place them right in front of the canvas. How do I work around it? Do I just make everything huge? So far nothing has worked. Any help would be appreciated. Thanks!

Start with your regular objects first: The spaceship, asteroid etc should be visible in your Main Camera. Next, you create a Canvas for your HUD elements, which should automatically be set so “Screen Space”, meaning it will draw on top of everything in the Main Camera game view. There is no physical relationship between the Canvas and other GameObjects. Your spaceship at scale 1 will probably be around the size of the default unit cube, but the Canvas will be a thousand times bigger. This is normal.
