A few cherry-picked (?) video clips showing that Richard Dawkins can't think of scenarios that prove that God exists, suddenly proves that God exists.
Surely, if God really existed then these conversations would be unnecessary and his existence would be obvious and an atheist would not be asked what is required to prove his existence.
If you and your theists mates can't prove the existence of God which you have failed to do, then relying on an atheist to do so is poor form.
