When items are on the same layer, they still have something called Z order, where they can appear above or behind on the same layer. Check out Z order bar (not available in free version) https://www.scirra.com/manual/157/z-order-bar. For a background though, a good practice is to have the background on layer 0, and then start putting the sprites on layer 1 and above, see Layers https://www.scirra.com/manual/42/layers-bar.
