The evidence for the resurrection of Jesus as an historical event is of very poor quality. It's no more capable of persuading an impartial onlooker that such an event happened in history than any other of the resurrection stories of antiquity.
The initial problem
An historical Jesus has never been definitively found. If in this thread I appear to speak as though he historically existed, it's only so as to discuss the evidence of the resurrection in isolation from this problem.
The 'Usual Story' problem
Resurrections are routine in tales from the ancient world.
In the bible stories -
* Samuel came back after his death and spoke with Saul. (You could argue he was a ghost, not a bodily resurrection.)
* Elijah raised the Zarephath woman’s son.
* Elisha raised the Shamite woman’s son.
* The man whose dead body touched Elisha's bones was resurrected.
* Jesus raised the Nain widow’s son.
* Jesus raised Lazarus.
* Peter raised Tabitha / Dorcas.
* Matthew describes the faithful dead at large in the streets of Jerusalem.
Elsewhere - and this is only a tiny sample - Osiris in Egypt, Tammuz in Babylon, Dionusos in Greece were put to death and came back to life. In Greece, Asklepios raised Lukourgos, Kapaneos and Tundareos from the dead, and Glaukos, Hippolutos and Orion were resurrected too - as indeed was Asklepios himself. Eurudike (and in Scandanavia, Baldur) nearly made it back. Persephone and Adonis had to spend only half their time in the Underworld.
The miracle problem
No examinable evidence suggests, let alone demonstrates, that supernatural beings exist in reality - gods, angels, souls, magicians, goblins, werewolves and so on, none of them.
But miracles are not just breaches of the rules of the natural world - they're purposeful interventions in the natural world by supernatural beings.
The evidence necessary to establish a miracle must therefore be of extraordinary quality - sufficient to establish a category never previously shown to exist. For that reason, virtually ANY non-supernatural explanation is vastly more probable than a supernatural one. (If you doubt this, next time you're hauled into court on a traffic matter, try running the defense, A supernatural being seized the controls from me.)
Hence (on the assumption that an historical Jesus existed at all) all of the following possibilities are vastly more probable explanations of the resurrection of Jesus than the supernatural ones in the NT -
1* The body of Jesus was never placed in the tomb.
2* The body of Jesus was stolen from the tomb.
3* Jesus wasn't dead. He recovered consciousness and left.
4* Whoever reported the body missing went to the wrong tomb.
5** or was mistaken
6** or altered his report to accord with his wishes
7** or set out to deceive.
8* Whoever spread the story of the missing body was acting on a false or mistaken report
9** or altered the report to accord with his wishes
10** or set out to deceive
11** or made up the story intending a metaphor
12** or made up the story but didn't intend it to be taken literally.
13* The story is a Jewish satire.
14* Or any other non-supernatural explanation.
Easy to see that it's impossible to rule any of them out on the basis of the NT accounts.
The incredibility of the NT accounts
Quite apart from the supernatural aspect, the five NT accounts are incredible for other reasons. If you went to court relying on evidence of that quality, you'd be thrown out before you could open your mouth.
First, none of the accounts is (or even purports to be) an eyewitness account.
Second, none of the accounts is contemporary with the event. If we use the traditional date for the crucifixion, 33 CE, then Paul's account is at least 17 years after the event and consists ONLY of the assertion that Jesus was crucified - he never says where, when, why or by whom. Mark's account is next, and no earlier than 70 CE, so at least 37 years later. John's (the last) is at least 67 years later.
Third, none of the NT accounts is an independent report. (And outside the NT, I discount the Testimonium Flavianum as very probably a forgery.)
And fourth, each of the five NT accounts of the resurrection conflicts in major ways with the other four.

Conclusion
You can get to the resurrection by faith.
You can't get there through history.
