Nothing can leave a “black hole;” no light, no matter, nothing. We can’t see it, can only determine its existence through supposed interactions with other entities, yet somehow astronomers are confident it exists. Sounds like a faith to me.
You can’t see the wind through your window, but a waving flag tells you it’s blowing...
The shadow cast on a wall tells you a person is standing around the corner...
Electrons you can’t see produce light when you flick a switch...
