Question Sprites missing from scene/game after drag & drop.

So I've been working on my project for a while now and the one thing I haven't figured out yet is why when I drag my sprites onto scene or hierarchy, they don't show up. This prevents me from using any kind of animations that are sprite sheets (Noobie here so probably just haven't figured out another way).

Well it does show up but it shows up as like one pixel, I really need to zoom in and even then it's always hidden behind all my layers. I have tried moving the sprite around and adjusting the Z axis. I've tried some of the things that a quick Google search suggested such as checking the basics but I haven't found any solution. The sprite only has "Transform" and "Sprite Renderer" after I drag it into scene. Any help is appreciated.
