Lots of gods claim resurrection, and if you believe Christianity, specifically Matthew 27, it happened to many people even in the gospels.
I'd recommend reading the New Testament in chronological order (Epistles first, then gospels, years they were written). If you're interested in being objective about it, you might have a different understanding.
That’s why I said that the death and resurrection was foretold in very intricate detail thousands of years before it happened. And the death and resurrection happened in the midst of enemies who would have loved to refute its factuality if they could but instead the news of it spread explosively starting right where the hostile witnesses could have torn it to bits if possible. It spread even with the threat of death to those who believed the claims about Jesus.
Why do you suppose that was? Why didn’t somebody simply go point out the body of Jesus in the tomb where it was laid?
The Gospels and Epistles seem to have been written around the same time - within the first 10-30 years after Jesus died and rose.
