You already have reliable sources to this via the gospels and I Cor 15. You also have the foundation of the church. The church has never existed without the resurrection.<quoted text>
I am saying this because whether or not there is a god I would need more evidence than the anonymous commentaries of superstitious people that believed the Earth was the center of the universe.
"The trouble with most people is that they think with their hopes or fears or wishes rather than with their minds." ~Will Durant
Have you read the " Testimony of the Evangelist" by Simon Greenleaf? "Greenleaf, one of the principle founders of the Harvard Law School, originally set out to disprove the biblical testimony concerning the resurrection of Jesus Christ. He was certain that a careful examination of the internal witness of the Gospels would dispel all the myths at the heart of Christianity. But this legal scholar came to the conclusion that the witnesses were reliable, and that the resurrection did in fact happen." You can find it here: http://www.bibleteacher.org/sgtestimony.htm
You should follow his example.
