What’s wrong with my phone?

I just need a diagnosis for my phone. There is a big spider web crack on the front camera and the stuff near it and the front camera is exposed. There are also cracks going down the screen. I wouldn’t mind these cracks, but the thing is, my phone won’t turn on. The power button does nothing at all. I think there’s something with the hardware. Someone help me diagnose this.

Can someone tell me why my iPhone won’t turn on?
