You might also be interested in the latest crazy claim, this time that the childhood home of Jesus has been uncovered in Nazareth. The evidence, presented by archaeologist Ken Dark, is that the house resembles one described in a seventh-century travelogue. This, logically, ought not to prove that it was the actual home of Jesus; at best, it proves that it was considered to be such in the 600s CE, which counts for pretty much nothing.
[Update: The following discussion grows out of a tradition recorded by Plutarch in the first century CE in his Life of Alexander 27.3 that "Alexander himself, in a letter to his mother, says that he received certain secret responses, which he would tell to her, and to her alone, on his return" (trans. Bernadotte Perrin). The contents of this letter, almost certainly a forgery, were apparently well known.]
Here is Cyprian describing it in Treatise VI, “On the Vanity of Idols,” sec. 3 (247 CE):
… Alexander the Great writes in the remarkable volume addressed to his mother, that through fear of his power the doctrine of the gods being men, which was kept secret, had been disclosed to him by a priest, that it was the memory of ancestors and kings that was (really) kept up, and that from this the rites of worship and sacrifice have grown up. (trans. Ernest Wallis)
Alexander the Great, the celebrated Macedonian, wrote in a remarkable document addressed to his mother, that under fear of his power there had been betrayed to him by the priest the secret of the gods having been men: to her he makes Vulcan the original of all, then the race of Jupiter. (trans. Ernest Wallis)
Herodotus, then, and Alexander the son of Philip, in his letter to his mother (and each of them is said to have conversed with the priests at Heliopolis, and Memphis, and Thebes), affirm that they learned from them that the gods had been men. […] But as Alexander and Hermes surnamed Trismegistus, who shares with them (the gods) in the attribute of eternity, and innumerable others, not to name them individually, [declare the same], no room is left even for doubt that they, being kings, were esteemed gods. (trans. B. P. Pratten)
28.5 …And, to treat Numa with all honor, let us mention as belonging to the same rank as these writings that which Alexander of Macedon wrote to his mother as communicated to him by Leo, an Egyptian high priest. In this letter not only Picus and Faunus, and Æneas and Romulus or even Hercules, and Æsculapius and Liber, born of Semele, and the twin sons of Tyndareus, or any other mortals who have been deified, but even the principal gods themselves, to whom Cicero, in his Tusculan questions, alludes without mentioning their names, Jupiter, Juno, Saturn, Vulcan, Vesta, and many others whom Varro attempts to identify with the parts or the elements of the world, are shown to have been men. There is, as we have said, a similarity between this case and that of Numa; for the priest being afraid because he had revealed a mystery, earnestly begged of Alexander to command his mother to burn the letter which conveyed these communications to her.
28.27 … For let those who will and can read the letter of Alexander to his mother Olympias, in which he tells the things which were revealed to him by the priest Leon, and let those who have read it recall to memory what it contains, that they may see what great abominations have been handed down to memory, not by poets, but by the mystic writings of the Egyptians, concerning the goddess Isis, the wife of Osiris, and the parents of both, all of whom, according to these writings, were royal personages. Isis, when sacrificing to her parents, is said to have discovered a crop of barley, of which she brought some ears to the king her husband, and his councillor Mercurius, and hence they identify her with Ceres. Those who read the letter may there see what was the character of those people to whom when dead sacred rites were instituted as to gods, and what those deeds of theirs were which furnished the occasion for these rites.

But if you’re an ancient astronaut theorist looking for proof that the “gods” were flesh and blood creatures, you’d think you’d do more with these kind of passages, especially when you have a celebrity like Alexander the Great endorsing your idea and finding alien “secrets” in Hermes’ tomb!
