Is there any set date that can be given for when Western civilization began?

1588 - The Sinking of the Spanish Armada

People who are more inclined to being furries than MLP fans.

Enlightenment, Industrial Revolution, Neo-Classical/Gothic architecture, Classical music, Representative Democracy etc

The defeat of Persia at the hands of the Hellenic League

Those are products of western civilization, not western civilization itself.

Aren't we a bit to different from them?
Just the Religious barrier should do a lot.

Minoan civilization is what I thought it would be, but I could be wrong.

In that case, probably Faustian Culture

The same driving force which made European's explore and conquer the globe, innovate in fields of music, art, architecture, science, economics, medicine etc. The same spirit which made Western civillisation the first to send men to outer space.

The love and desire for infinity, "boundless space", represented by the Gothic cathedral with a tall spire reaching up towards the heavens, which exists throughout Europe.

It really doesn't
Even the east west divide is based on location relative to the Bosphorus straits

Greek defeat of Persia .Roman defeat of Carthage during the Second Punic war. Or even if you wanna really stretch it... The Battle of Actium

Honestly? The Greek city states and the Roman Republic are where western civilization really started.

You could say about the time of the Venus of Wullendorf
