Regardless of the level of proof that a tomb was found empty, the answer
cannot be "It was supernatural powers," until supernatural powers are
proven first.
This is really the basic, central, or critical point of proving ANYTHING related to the "Story" of Jesus.
The Central Feature is not really about Jesus or his resurrection, but instead it's about a Supreme Being, aka Jehovah who intervene by resurrecting a man named Jesus, and by this means is going to save every single human who has ever lived on the planet, approx 100 billion people have lived and died on the planet earth.
If he plans to have them resurrected to heaven, then we have to ask why? Why not create them in heaven in the first place.
If resurrected on earth, why did some All Knowing, all Powerful, God of love tolerate so much suffering and pain on billions of innocent children, mothers, fathers and even the trillions of innocent animals------FOR THOUSANDS OF YEARS and continuing.
This is not a "Picture" of an All Knowing, All Powerful God of Love.
It is a picture of man made stories to quell the reality of death in the absence of a Loving and just Supreme Being.
An All Powerful God with Supernatural Powers HAS NEVER BEEN PROVEN.
On the other hand there are MANY Unproven stories of many Powerful Gods like Zeus, God of the sky, lightning, thunder, law, order, justice, King of the Gods and the “Father of Gods and men”. and so many others with different supernatural powers like Atlas, Chaos, Eros, Pan, etc.
The idea of a sacrifice needed to appease Some powerful deity was a common belief of ancient people.
Jehovah was just another deity that required the sacrifice of animals and humans to appease him. He loved the smell of blood.
But thankfully, we are slowly coming out of such ignorance.I think in another few hundreds years, humankind will grow out of it.
Genesis 8
And Noah built an altar to the Lord and took of every clean [four-footed] animal and of every clean fowl or bird and offered burnt offerings on the altar.
21 When the Lord smelled the PLEASING ODOR [a scent of satisfaction to His heart],
ERVThe Lord smelled these sacrifices, AND IT PLEASED HIMAnd Jephthah made a vow to the Lord and said, If You will indeed give the Ammonites into my hand, Then whatever or
whoever comes forth from the doors of my house to meet me when I return
in peace from the Ammonites, it shall be the Lord’s, and I will offer
it or him up as a burnt offering. ...Then
Jephthah came to Mizpah to his home, and behold, his daughter came out
to meet him with timbrels and with dances! And she was his only child;
beside her he had neither son nor daughter.
35 And
when he saw her, he rent his clothes and said, Alas, my daughter! You
have brought me very low, and you are the cause of great trouble to me;
for I have opened my mouth [in a vow] to the Lord, and I cannot take it
back.....At the end of two months she returned to her father, who did with her according to his vow which he had vowed
