That's like saying that had Asia never existed, Korean bbq would never be eaten. You can't tell either way. The world is such a random place and the most trivial of events can have profound impact on seemingly unrelated others (also known as

Concepts such as a Messiah descending into our world in a particular point in time and space, some final Judgement preceded by fire and brimstone... The Judeo-Christian tradition gave us the notion of linear time. I honestly cannot tell how, why and if the same would've happened under different conditions, in a different world, with different people...
