This is a good example of the absurdity which is the mark of Preterism.
The Bible is very clear that God has allotted just 3 1/2 years (42 months, 1260 days, time, times, and half a time or the dividing of time) to the reign of the Antichrist. (time = 1 year + times = 2 years + half a time = 6 months.)
And he [the Antichrist] shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time. (Dan 7:25)
And there was given unto him [the Antichrist] a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months. (Rev 13:5)
And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished. (Dan 12:7)
And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent. (Rev 12:14)
But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months. And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. (Rev 11:2,3)
So to claim that he is has been around for over 2,000 years is total nonsense.
