Jesus is the most well attested person of the first century in literary sources.
Jesus is the least documented wrt first-hand accounts ... at zero documents. There is literally no one with less first-hand account documentation. It's like you are forcing people to think of Jesus as an urban legend.
The existing evidence convinces me that that it's more probable than not that the testimony of Matthew, Mark, Paul, John, Luke, Clement, Ignatius, Polycarp are the attestations of eyewitnesses,
First, you have to explain how you established this probability.
Second, you have to admit that there is no probability because it's just your opinion.
Third, you still have to get a time machine to travel back in time and verify your claim.
You have no first-hand accounts.
There are no eyewitness, first-hand accounts of Alexander the Great.
There are countless accounts, just not in the form of a manuscript. The coins he minted, of which we have thousands:
There are many royal decrees such as the following:

Translation:
When the ambassadors returned from
Persis,
those who had represented the interests of the
Philippians and their land
before
King Alexander, and Alexander rendered judgment concerning them:
that the
Philippians are to work the
argos land which belongs to them,
and that they are to pay tribute for the
argos land.
And he appointed
Philotas and
Leonnatos to define the boundaries
of the
argos land for them.
And as for the
Thracians who have encroached upon the ancient land
which
Philip had given to the Philippians,
Philotas and Leonnatos are to investigate
whether they encroached
before Philip’s boundary decree
or
after they encroached.
And if they encroached
after, they are to withdraw.
And Philotas and Leonnatos are to remove
two thousand plethra from the
argos land …
… of the land of
Daton to add from this land,
measuring out
two stades.
The rest of the land is to be held by the
Philippians,
but whatever has been granted to the
Thracians by Philip,
the Thracians are to harvest,
just as Alexander has ruled concerning them.
And the Philippians are to hold the land
… as the hills lie on either side …
And as much land as lies around
Siraike and
Dainēron,
the Philippians are to possess,
just as Philip granted.
But the
timber in
Dysōros is not to be sold
until the embassy returns from Alexander.
And the
marshes are to belong to the Philippians
as far as the bridge.
Alexander the Great founded cities whose founding was documented. We have the cuneiform documented death of Alexander the Great by the Babylonians, so we know the day he died.
