Let’s turn that on its head and ask: Why do some put so much value in the crucifixion of a Roman prisoner? The Romans crucified men by the hundred, or was it by the thousand. Why do you think one special Roman prisoner came to life after he died? What made him special anyway? How do you know he existed in the first place?
If you provide empirical or authentic extra-biblical literary evidence of this crucifixion and resurrection, I’ll revisit your question. I may quite possibly change my mind if real evidence comes to light, but it must be proven to be real. Fair enough?
