I think there is more evidence for Jesus resurrection than for many historical events that are accepted with little question, based on far fewer eyewitnesses.
An eyewitness account in 1 Corinthians is not proof. It could be categorized as evidence in the form of information, but a rather unreliable evidence.
No court in the modern world will accept an eyewitness account of supernatural events in light of the scientific progress of our age.
In addition, in light of the scientific impossibility of physical resurrection, the logical conclusion is that this eyewitness account is planted by scribes and editors in order to promote a subjective dogma. Or a second option that this was an ancient hearsay mixed with the passions of the followers of an ancient Galilean teacher.
Out of curiosity, which historical events do you consider to be accepted with less evidence than the resurrection of Jesus?
Another question I pose is. Should a modern court accept eyewitness testimonies and accounts that claim supernatural events?
For example, is it enough to have eyewitness accounts of duplicating a handful of fish and loafs of bread into thousands, or walking on water, or turning water into wine in order for these claims to be accepted by modern academic institutions as a reality?
Think how much more vague descriptions of eyewitness accounts in 2000 year old texts are. Texts which their sole mission is based on a supernatural event such as the resurrection and promoting it as truth.
BTW, I'm not here to test your faith. I simply wish to make you ponder why an eyewitness account in an ancient text which promotes the resurrection as a dogmatic truth might be rejected as reliable evidence, and certainly might be rejected as proof.
