Matthew chap.27: 45 "Now from the sixth hour there was darkness over all the land unto the ninth hour." 27:51-53 "And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; and the graves were opened; and many bodies of the saints which slept arose, and came out of the graves after his resurrection, and went into the holy city and appeared unto many."
None of the other Gospels mention the darkness all over the land, the veil of the temple rent in twain top to bottom, the earthquake, the rocks, the graves opening and dead saints who rose and walked out of their graves.
Nor did any historian living in the same place and time as these events supposedly happened.
