One thing that does not make sense to me about Christianity is even if you believe the 500 witnesses, the Bible itself introduces you to someone who can control thousands, as Legion.
Legion, in the Bible, by using "legion" as his name implies he (or they if you are going to deny weird mathematics to anyone other than God) can control thousands as a legion is around 5,000 men. What's more, is the Bible confirms him.
In Legion's first appearance, nothing is out of the ordinary when he speaks, as it is only him speaking.
And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many.
However, later an interjection by scripture itself corroborates Legion's words.
And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him.
And the most problematic is later in the first appearence, when Legion is confirmed without doubt to be able to control thousands independent of his name, and completely unnecessarily to the story
And forthwith Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two thousand;) and were choked in the sea.
Also, the text logically implies Legion himself killed the pigs, not the water, as it uses choke instead of drown. Also, pigs can swim.
So how have major Christian groups like the Southern Baptist Convention explained why God thinks 500 witnesses are convincing, when someone who can control thousands exists?
