My paralysed aunt was healed through prayer, a famous Church in Albania does miracles every year, and many other miracles have been witnessed. How can this be if there is no God?

The Miracle of Fatima was also 'witnessed', yet there are entirely non-supernatural explanations for what was described. Simply because something is witnessed doesn't mean that it is exactly what people say it is.

Some pertinent questions:

1. To what extent was she paralysed? Did she have any movement or control of movements?

2. What medical records are there to confirm both the previous diagnosis and current status?

3. Is she still walking around now?

Derren Brown has an excellent video explaining how faith healers work.

The other thing I'll add is that why do we only see miracles for ailments that are unseen? At faith healing meetings, we never see amputees grow limbs, we never see skin graft itself and we never see eyes grow in place of glass eyes.
