The earliest accounts of Jesus were written 20-40 years after his supposed death, and the other gospels were written much later. They were also 2nd or even 3rd hand accounts. It is very obvious that they plagiarised from multiple other religions such as Paganism, in many cases contradict one another, and scholars will tell you that many are just tropes from that time period. The earliest resurrection story novel is 'Callirhoe' by Chariton of Aphrodisias, in which the basic gist is where a man murders his wife, she is buried in a tomb, pirates rob her tomb only to find her alive, and end up taking her with them. People find out that the tomb is open and that she has mysteriously disappeared. Sound familiar? Grave robbing was very common at that time, so it's no surprise people would find tombs open and empty.
