Does a God exist?

[Angrboda]

I don't have any reason to think they are lying, so I believe they happened, therefore I believe there is evidence for the existence of God. 

There is abundant evidence that these were times replete with kooks and quacks of all varieties, from sincere lunatics to ingenious frauds, even innocent men mistaken for divine, and there was no end to the fools and loons who would follow and praise them.

You have plenty of reason to doubt that the miracles in the NT happened, you just choose not to exercise those reasons with regard to the NT. You doubt that Joseph Smith talked to an angel. You doubt that Mohammed did likewise. You choose not to exercise those doubts with respect to the NT. That makes you guilty of special pleading and your conclusions are therefore not reliable. You treat the truth claims of the NT differently than you do other truth claims. That's simply being biased.
