Why Should Someone Be an Atheist?

[Esquilax]

Is the Bible just making a claim or is it using testimony, both oral and written?

Oral and written testimony are two of the most common ways that people make claims.

Besides, would you take any other claims of magic true, if they were written by anonymous authors with no corroboratory testimonies outside of those claims, without the level of popularity christianity enjoys? Because, I mean, all those old legends of Zeus are also anonymously written by ancient peoples that claim to be true. Is that enough for you to believe in Zeus?
