Prophecy is the most irrefutable evidence
In the context of the prophecy of the coming of Cyrus (as confirmed in history) we find this statement:
20 “Come, gather together,
Isaiah 45:20-22
and approach, you fugitives of the nations.
Those who carry their wooden idols
and pray to a god who cannot save
have no knowledge.
21 Speak up and present your case[i]—
yes, let them consult each other.
Who predicted this long ago?
Who announced it from ancient times?
Was it not I, the Lord?
There is no other God but me,
a righteous God and Savior;
there is no one except me.
22 Turn to me and be saved,
all the ends of the earth.
For I am God,
and there is no other.
Only God could know and tell the future exactly years before it happened. The very specific particulars of Cyus as found in the Bible is just one confirmed example of the future being foretold in specific detail (not general like today’s psychics).
