Why are events that happen only once difficult to analyze from a scientific point of view?

Question

please answer. thank you so much

Answer 1

Science POV is to take a 'theory' (which can be an explanation to a one off event) and make it 'proven' and then a scientific 'law'.

So to make a 'law' (or scientifically prove something) from a one off event which cannot be explained by other known scientific laws mean that it cannot of itself be proven (or analyzed as you put it)

They can be analyzed, but not necessarily proven which is the purpose of the scientific POV.

For example, gravity is a scientific and mathematical law. If is was experienced once and never repeated, then it would be difficult to analyze because the 'theory' of gravity is dis-proven when it is not repeated.

Answer 2

Because you don't have the chance to repeat them and change a single variable each time.  That is how you determine what factors affect the event.  This could lead you to enough of an understanding to determine the cause of the event and to predict the sorts of things that would happen when you combined those factors in a certain way.

Answer 3

Because scientific analysis requires events to be repeatable, or  at least the effects of an event to be repeatable.  You can't extrapolate from one data point.  If something happens only once, it's very difficult (if not impossible) to determine it's cause or predict it's effects.
