Atheists, what evidence for God would be enough?

There are people who will affirm that they had very specific prayers answered....but you won't believe. People claim miraculous healings....but you won't believe. People have heard an audible voice of God speaking...but you won't believe. People have SEEN ANGELS...but you won't believe. Yes, I know, you have not seen or heard these things....but even if you had, your fellow atheists would just say that you've been poisoned by the theists....and they would not believe YOU. So just when is the evidence enough?
