Beside, he did return to them right after he was resurrected and show himself to them and walk through walls and show his wounds.
All of the accounts say something different. Not a reliable narrative and if one is true, then at least two of the Gospels are wrong. Parts of the Bible claim he was raised purely as a spirit and other claims he was raised in a physical body. Which is it?
He also said he would send the holy spirit as a helper and his father and he would come to dwell with people and be with them and reside with them and they would all be one and things would go on through wars and various tribulations and not to think when there were false Christs that it was him returned, he indicated it would be generations away, he said it was a distant time and no one knew when not even him, so where did he lie ?
That's a theological argument and not something has historical meaning that can be objectively tested for truth.
Some things he said referred to the destruction of the Temple in AD 70 and it has not been rebuilt to this day, in fact the Dome of the Rock, a Muslim mosque, sits on the Temple mound.
The temple had been destroyed before. Jerusalem was occupied and in a state of conflict. Jesus himself was preaching destruction (along with many many other apocalyptic Jews). It was a general statement that didn't have any specific information like a specific date, who would be doing the destruction, etc. What kind of special prophetic knowledge did that require?
