Between Premil and Amil, and since both positions can't be the correct one, one of them has to be false teaching, obviously. Why can't it be Amil? Why does it have to be Premil that is false teaching?
In another post of yours you suggested that Barnabas was an Amil. Let's look at something he wrote. Who today would more than likely support what he wrote here below? Premils or Amils?
------------------------
Barnabas 15:2
And in another place He saith; If my sons observe the Sabbath then
I will bestow My mercy upon them.
Barnabas 15:3
Of the Sabbath He speaketh in the beginning of the creation; And
God made the works of His hands in six days, and He ended on the
seventh day, and rested on it, and He hallowed it.
Barnabas 15:4
Give heed, children, what this meaneth; He ended in six days. He
meaneth this, that in six thousand years the Lord shall bring all
things to an end; for the day with Him signifyeth a thousand years;
and this He himself beareth me witness, saying; Behold, the day of
the Lord shall be as a thousand years. Therefore, children, in six
days, that is in six thousand years, everything shall come to an end.
Barnabas 15:5
And He rested on the seventh day. this He meaneth; when His Son
shall come, and shall abolish the time of the Lawless One, and shall
judge the ungodly, and shall change the sun and the moon and the
stars, then shall he truly rest on the seventh day.
Barnabas 15:6
Yea and furthermore He saith; Thou shalt hallow it with pure hands
and with a pure heart. If therefore a man is able now to hallow
the day which God hallowed, though he be pure in heart, we have gone
utterly astray.
Barnabas 15:7
But if after all then and not till then shall we truly rest and
hallow it, when we shall ourselves be able to do so after being
justified and receiving the promise, when iniquity is no more and all
things have been made new by the Lord, we shall be able to hallow it
then, because we ourselves shall have been hallowed first.
Barnabas 15:8
Finally He saith to them; Your new moons and your Sabbaths I cannot
away with. Ye see what is His meaning ; it is not your present
Sabbaths that are acceptable [unto Me], but the Sabbath which I have
made, in the which, when I have set all things at rest, I will make
the beginning of the eighth day which is the beginning of another
world.
Barnabas 15:9
Wherefore also we keep the eighth day for rejoicing, in the which
also Jesus rose from the dead, and having been manifested ascended
into the heavens.
The Epistle of Barnabas (translation J.B. Lightfoot)
----------------------------
For example, verse 4 above. What Amil today agrees with the following from that verse, thus supports it----He
meaneth this, that in six thousand years the Lord shall bring all things to an end; for the day with Him signifyeth a thousand years; and this He himself beareth me witness, saying; Behold, the day of the Lord shall be as a thousand years. Therefore, children, in six days, that is in six thousand years, everything shall come to an end?
He obviously took this thousand years as a literal thousand years. How many Amils today take the thousand years as a literal thousand years?
Let's look at verse 8 and the following---it is not your present Sabbaths that are acceptable [unto Me], but the Sabbath which I have made, in the which, when I have set all things at rest, I will make the beginning of the eighth day which is the beginning of another world.
Does that support Premil or Amil? Per Premil there would be an eighth day. Per Amil there wouldn't be. If there are 6000 years in this age, according to Barnabas, and that there is then a day of rest, the 7th day, then after that the beginning of a new world, meaning the eighth day, how can the 7th day not be meaning the thousand years in Revelation 20, per Barnabas' position? How can Barnabas have been Amil rather than Premil?
