most important historical event of past 200 years

Hard not to say World War II. You could make a respectable argument for World War I, if your position is that WWII was a natural consequence of the outcome of WWI.

I'm not sold on things like "the birth of Einstein" - my view is that objective reality would have been discovered and described without any specific individual, merely a few years later.

I would say the advent of antibiotics going by what we know. If it's something that's being kept from us, it could be contact with extraterrestrial beings.

Probably the 'invention' of harnessing and using electricity.

In the medium to long term : World War 2. In the extremely long term : perhaps the birth of Einstein.
