It was not my point, but you are correct, there are other doctorates other than PhD.

Technically medicine/physiology makes up a number of sciences so not all sciences hand out PhDs, some hand out MDs.

According to the rules you can post something without link to some exterior resource as long as you abide by rule 2.

Originally, and well into the 19th century, "Dark Ages" meant a time of cultural decline (following the negative view with which Petrarch and other Renaissance scholars held for the time separating them from their venerated ancients). This changed with the rise of professional scholarship in history in the 19th and 20th centuries where instead the lack of sources as well as a perceived lack of quality in the sources (as compared with the illustrious historians of Ancient Rome and Ancient Greece) became the important characteristics behind the term "Dark Ages". As of today most historians avoid the term as far as possible in favor for the less judgemental "the Early Middle Ages".

*Pontius Pilate. As for truth there is no general agreement whatsoever but a lot of competing theories. I recommend you take a look at https://plato.stanford.edu/entries/truth/ to get some overview.

>Caesars were emperors, just of a lower, junior grade to Augustuses

Only after the reform of Diocletian, the so-called tetrarchy. Before the tetrarchy Caesar was reserved for the emperor and occasionally for his to be successor (from the time of Hadrian to the reign of Diocletian). Originally Caesar was used for all male members of the imperial family (Augustus to Hadrian). Since the coin is from before Diocletian, Caesar means that it refers to an emperor.

edit: rephrased the last sentence.

If that's the case, then it seems a bit off and I can see how it can come across as cringe-y. Kinda suggests to me that he's using it as a crutch.

Prehistory is an accepted term and quite harmless as well. It just means the time before we have written sources (which can vary for different places). Why he would need to repeat it often is weird but as with so many cranks it might be just to pad the run time; when there's not much substance to a theory (and there never is with conspiracy theories) there is always a need for repetition, redundancy and futile exercises in pedantry.

There are plenty of lacunae for those two civilizations as well despite what has survived. For certain times the dearth of sources is almost complete and mere conjecture the best that can be offered.

Tattooing is considered marking, not branding.

The opposite would be humanely branded, I'm sure.

Papyrus, while not exactly cheap, was not expensive either. Sure, a long roll would cost you, but shorter formats would have been easily affordable to most. Most of the extant papyri fragments testify to this, as ca 90 % are letters, archival notes, records, accounts, and contracts. Every day use objects in other words. Vellum and parchment on the other hand were much more expensive.

No, some of it survived due to very special circumstances, see for example Oxyrhynchus papyri, https://en.m.wikipedia.org/wiki/Oxyrhynchus_Papyri, Herculaneum papyri, https://en.m.wikipedia.org/wiki/Herculaneum_papyri.

Wax tablets were only for temporary notes. You wiped it clean when you were done, and then it was ready to be reused, so you only needed one. Books, and more permanent texts, were written on papyrus scrolls and later also on parchment. Scrolls were stored in wooden boxes with labels, one scroll per box. Scrolls could not have as much texts as our books today (that they only wrote on one side made sure of that) and literary works of considerable length made up several scrolls. For example, nowadays we can get Plato's Republic in one book, but back then it consisted of 10 scrolls (and also ten wooden boxes). As a vestige Plato's Republic is still divided not in chapters, but in books (marked with Roman numerals; this is also the case with many other works from antiquity).

Suetonius reports two traditions. According to one Caesar says nothing, according to the other he says "and you, son" in Greek. Suetonius doesn't elaborate on these traditions nor does he show preference for one over the other. One might note the similarity with the quote "the die is cast" (when Caesar crossed the Rubicon) which Plutarch claims Caesar uttered in Greek and not in Latin (it seems Caesar choose the quote from a play by the Greek playwright Menander).
