Suppose one thousand years is symbolic.
Dialog
Sam: So you say that Satan is bound for a thousand years?
Doug: No. We don't know how long Satan will be bound. The thousand years just represents a really, really long time.
Sam: So if you don't know how long it will be, why mention time at all? Why give a number? He is released when he is released.
Doug: No, but don't you see, it lasts a really, really long time. We don't know how long, but it's a long time.
Sam: Okay, it's a really long time. But why speculate on a time? Are you being optimistic? Is your estimate over-exaggerated or understated?
Doug: Didn't I say? Oh, I must have forgotten.
Sam: What do you expect us to do with your "estimate"? What does it matter how long it is?
Doug: Hmm. I don't know. The point is, its a really long time.
Sam: You say Satan will be released. Why let him go? What is THAT all about?
Doug: Satan's imprisonment is temporary.
Sam: Okay, that's my point. Why is it temporary? Is everything during the thousand years temporary?
Doug: Well . . .
Sam: It says here that some people will live and reign with Christ during that period. Is that also a temporary condition?
Doug: No.
Sam: Well, if the thousand years represent a temporary condition with respect to Satan's binding, how can you say that it doesn't represent other temporary conditions, such as living and reigning with Christ? Again, why specify a fixed amount of time?
It seems to me that since a thousand years involves a cardinal number followed by years, that Amils then need to provide at least one example anywhere in the Bible where a cardinal number is followed by years, that the amount of years specified is not literally meaning the amount of years specified, it is symbolizing something else instead, in order to support their theory pertaining to a thousand years.
Some random examples below. Do any of these support their theory pertaining to the thousand years, that the number of years specified in these examples below, that in some of these verses the amount of years specified are not literally meaning the amount of years specified?
Genesis 5:3 And Adam lived an hundred and thirty years, and begat a son in his own likeness, after his image; and called his name Seth

Hebrews 3:9 When your fathers tempted me, proved me, and saw my works forty years.
These are just random ones I picked out. Maybe I just got unlucky here and only found ones that don't support what Amils allege about a thousand years, that the amount of years specified isn't literally meaning the amount of years specified. Maybe they should have a go at then since there are plenty more examples of verses involving a cardinal number followed by years, and that maybe they can find at least one example that supports their theory, that in the Bible, when a cardinal number is followed by years, that in some cases the amount specified isn't literally meaning the amount specified.
But instead of them doing that, what do they typically do? They provide examples involving a thousand, and then say, see, a thousand is not literally meaning a thousand here. Except none of us are claiming otherwise to begin with, in regards to these examples they provide.
What they are not doing per these examples is proving that when a cardinal number is followed by years in the Bible, that there are some instances that the amount specified is not literally meaning the amount specified since none of these examples pertaining to a thousand they are submitting as proof that a thousand isn't literally meaning a thousand every time are even involving years, thus a cardinal number followed by years. IOW, it's like comparing apples to oranges.
