Early Christians did not care much to use/acquire such an argument that “Jesus's missing body proves he rose”. [Full page].
This is relevant because people generally do not try convincing others of a lie when they lack motivation.1
Any Christian would have known that a lie saying “Jesus's body is gone” was stupidly falsifiable.1 This is relevant because Christian liars would not choose to tell a stupidly falsifiable lie.
Christians were not spinning tempting lies which would have clearly been equal or better for “proving” that Jesus resurrected.1 This is obviously relevant because, if the goal was to support Jesus's resurrection, one of those more tempting lies would have been use instead.
