1. What is Buddhism's take on miracles of other religions.
Siddhis exist in all religions.
...I'll use the last known by me, verified miracle I am aware of which is Fatima(1930s). Are these Deva's messing arround
There are other beings besides "Devas". Nagas, Yaksas, Asuras, etc.
2. How would Buddhism explain the subjective "evidence" of ghosts/spirits, typically these experiences are not describing Hungry Ghosts, but rather disembodied personalities which would go against anatta.
The existance of "spirits" doesn't go against the idea anatman
anymore than the existance of human beings.
