Dear Christians: Please name One Eyewitness to the Crucifixion who was still alive in 70 AD

Two of the biggest assumptions that many Christians make regarding the truth claims of Christianity is that, one, eyewitnesses wrote the four gospels.  The problem is, however, that the majority of scholars today do not believe this is true. The second big assumption many Christians make is that it would have been impossible for whoever wrote these four books to have invented details in their books, especially in regards to the Empty Tomb and the Resurrection appearances, due to the fact that eyewitnesses to these events would have still been alive when the gospels were written and distributed.

But consider this, dear Reader:  Most scholars date the writing of the first gospel, Mark, as circa 70 AD.  Who of the eyewitnesses to the death of Jesus and the alleged events after his death were still alive in 70 AD?  That is four decades after Jesus’ death.  During that time period, tens of thousands of people living in Palestine were killed in the Jewish-Roman wars of the mid and late 60’s, culminating in the destruction of Jerusalem.

How do we know that any eyewitness to the death of Jesus in circa 30 AD was still alive when the first gospel was written and distributed in circa 70 AD?  How do we know that any eyewitness to the death of Jesus ever had the opportunity to read the Gospel of Mark and proof read it for accuracy?

I challenge Christians to list in the comment section below, the name of even ONE eyewitness to the death of Jesus who was still alive in 70 AD along with the evidence to support your claim.

If you can’t list any names, dear Christian, how can you be sure that details such as the Empty Tomb, the detailed resurrection appearances, and the Ascension ever really occurred?  How can you be sure that these details were not simply theological hyperbole…or…the exaggerations and embellishments of superstitious, first century, mostly uneducated people, who had retold these stories thousands of times, between thousands of people, from one language to another, from one country to another, over a period of many decades?
