You don't mention anything specific, but were just vague. Very specifically, the original Apostles said they saw Jesus resurrected, people don't willingly die for something they know is a lie, and group hallucinations are impossible.

Can you find naturalistic explanations for everything Chris Angel does?

With all the eye witnesses Chris Angel has, he must be really walking on water. Or could group hallucinations be possible?

I have 17 non-Christian sources within 150 years of Jesus' death. Let's start with Tacitus.
Tacitus, sufficient reason is uncovered to doubt this Roman author's value in proving an "historical" Jesus. In his Annals, supposedly written around 107 CE, Tacitus purportedly related that the Emperor Nero (37-68) blamed the burning of Rome during his reign on "those people who were abhorred for their crimes and commonly called Christians." Since the fire evidently broke out in the poor quarter where fanatic, agitating Messianic Jews allegedly jumped for joy, thinking the conflagration represented the eschatological development that would bring about the Messianic reign, it would not be unreasonable for authorities to blame the fire on them. However, it is clear that these Messianic Jews were not (yet) called "Christiani." In support of this contention, Nero's famed minister, Seneca (5?-65), whose writings evidently provided much fuel for the incipient Christian ideology, has not a word about these "most-hated" sectarians.
In any event, the Tacitean passage next states that these fire-setting agitators were followers of "Christus" (Christos), who, in the reign of Tiberius, "was put to death as a criminal by the procurator Pontius Pilate." The passage also recounts that the Christians, who constituted a "vast multitude at Rome," were then sought after and executed in ghastly manners, including by crucifixion. However, the date that a "vast multitude" of Christians was discovered and executed would be around 64 CE, and it is evident that there was no "vast multitude" of Christians at Rome by this time, as there were not even a multitude of them in Judea. Oddly, this brief mention of Christians is all there is in the voluminous works of Tacitus regarding this extraordinary movement, which allegedly possessed such power as to be able to burn Rome. Also, the Neronian persecution of Christians is unrecorded by any other historian of the day and supposedly took place at the very time when Paul was purportedly freely preaching at Rome (Acts 28:30-31), facts that cast strong doubt on whether or not it actually happened. Drews concludes that the Neronian persecution is likely "nothing but the product of a Christian's imagination in the fifth century." Eusebius, in discussing this persecution, does not avail himself of the Tacitean passage, which he surely would have done had it existed at the time. Eusebius's discussion is very short, indicating he was lacking source material; the passage in Tacitus would have provided him a very valuable resource.
Even conservative writers such as James Still have problems with the authenticity of the Tacitus passage: For one, Tacitus was an imperial writer, and no imperial document would ever refer to Jesus as "Christ." Also, Pilate was not a "procurator" but a prefect, which Tacitus would have known. Nevertheless, not willing to throw out the entire passage, some researchers have concluded that Tacitus "was merely repeating a story told to him by contemporary Christians."
Based on these and other facts, several scholars have argued that, even if the Annals themselves were genuine, the passage regarding Jesus was spurious. One of these authorities was Rev. Taylor, who suspected the passage to be a forgery because it too is not quoted by any of the Christian fathers, including Tertullian, who read and quoted Tacitus extensively. Nor did Clement of Alexandria notice this passage in any of Tacitus's works, even though one of this Church father's main missions was to scour the works of Pagan writers in order to find validity for Christianity. As noted, the Church historian Eusebius, who likely forged the Testimonium Flavianum, does not relate this Tacitus passage in his abundant writings. Indeed, no mention is made of this passage in any known text prior to the 15th century.
The tone and style of the passage are unlike the writing of Tacitus, and the text "bears a character of exaggeration, and trenches on the laws of rational probability, which the writings of Tacitus are rarely found to do." Taylor further remarks upon the absence in any of Tacitus's other writings of "the least allusion to Christ or Christians." In his well-known Histories, for example, Tacitus never refers to Christ, Christianity or Christians. Furthermore, even the Annals themselves have come under suspicion, as they themselves had never been mentioned by any ancient author.
It is a peculiar and disturbing fact that the entire Annals attributed to Tacitus never existed until their discovery by Johannes de Spire, at Venice in 1468, and that this sole copy, purportedly made in the 8th century, was in his possession alone. The history of the Annals begins with the Italian calligrapher, Latin scholar and Papal secretary Gian Francesco Poggio Bracciolini (1380-1459), who, writing in 1425, intimated the existence of unknown works by Tacitus supposedly at a Benedictine monastery in Hersfeld, Germany. "The Annals" was subsequently "discovered" in a copy of Tacitus's Histories at the monastery, in the sixteenth century. This text was not named "Annals," however, until 1544, by Beatus Rhenanus.
In 1878, the "excellent Latin scholar" WJ Ross wrote the book Tacitus and Bracciolini, which evinced that the entire Annals were a forgery in very flawed Latin by Bracciolini in the 15th century. Ross's work was assailed by various clergymen, who claimed the main defect in his argument was that "one of the MSS. [manuscripts] of the Annals is at least as early as the XI century." In reality, the critics had not actually read Ross's book, in which Ross does indeed address this purported 11th century manuscript, which he shows was merely pronounced by dictum to be early. Interested readers are referred to Cutner and Ross's books for further discussion of this debate, which includes, in Ross's dissertation, a minute examination of the Latin of the Annals. Suffice it to say that the evidence is on the side of those who maintain the 15th century date, in that the Annals appear nowhere until that time.
In any event, even if the Annals were genuine, the pertinent passage itself could easily be an interpolation, based on the abundant precedents and on the fact that the only manuscript was in the possession of one person, de Spire. In reality, "none of the works of Tacitus have come down to us without interpolations." Drews considers the Tacitus passage in its entirety to be one of these forgeries that just suddenly showed up centuries later, and he expresses astonishment that "no one took any notice during the whole of the Middle Ages" of such an important passage. Says he:
No one, in fact, seems to have had the least suspicion of its existence until it was found in the sole copy at that time of Tacitus, the Codex Mediceus II, printed by Johann and his brother Wendelin von Speyer about 1470 at Venice, of which all the other manuscripts are copies.
The reason for this hoax may be the same as the countless others perpetrated over the millennia: The period when the Annals were discovered was one of manuscript-hunting, with huge amounts of money being offered for unearthing such texts, specifically those that bolstered the claims of Christianity. There is no question that poor, desperate and enterprising monks set about to fabricate manuscripts of this type. Bracciolini, a Papal secretary, was in the position to collect the "500 gold sequins" for his composition, which, it has been claimed was reworked by a monk at Hersfeld/Hirschfelde, "in imitation of a very old copy of the History of Tacitus."
Regarding Christian desperation for evidence of the existence of Christ, Dupuis comments that true believers are "reduced to look, nearly a hundred years after, for a passage in Tacitus" that does not even provide information other than "the etymology of the word Christian," or they are compelled "to interpolate, by pious fraud, a passage in Josephus." Neither passage, Dupuis concludes, is sufficient to establish the existence of such a remarkable legislator and philosopher, much less a "notorious impostor."
It is evident that Tacitus's remark is nothing more than what is said in the Apostle's Creed--to have the authenticity of the mighty Christian religion rest upon this Pagan author's scanty and likely forged comment is preposterous. Even if the passage in Tacitus were genuine, it would be too late and is not from an eyewitness, such that it is valueless in establishing an "historical" Jesus, representing merely a recital of decades-old Christian tradition.
