So it seems that there’s a deadline: God’s only going to give us 8510 years (plus however many there were BC, I guess), and then he’s going to pass judgement on the whole Human Race Project, and like as not toss the whole thing out and start over.
Or so Zager and Evans would have us believe. The fact that there’s a next verse to this song, taking us even further into the future, tends to belie the danger of God returning to square one here.
