Naomi I believe if there had been a resurrection all the Gospels would be shouting about it , and Mark in particular , as his was the exemplar for the others. It is also held up by biblical scholars as the most valid and reliable of all the Gospels. He never mentioned the nativity nor the resurrection nor the ascension. Matthew who took much from Mark only added a very short mention one verse and little or no detail.
It was this total absence of the resurrection and ascension that caused the early church to question it and add their own ending, which was based on Lukes , and as can be seen it is only Luke and the forged ending of Mark that mentions in one line the ascension.
Mark's Gospel was the first to be written of which over 300 verses were largely copied and added to by the others , with a great deal of cross fertilisation between Matthew and Luke.
For what it is worth IMO if an event wasn't even mentioned in Mark it probably never happened in the way the later Gospels described
I haven't mentioned John because that was the Harry Potter version of the others . It was a compilation by the Society of John of generalities compiled by many priests over decades to suit the Jesus cult.
