Proving Philosophy

If you could really prove something substantial in philosophy it wouldn't be philosophy.
For example - lets say I prove (imagine a physical experiment) or that mind exists independent of the body, or god comes down to earth and says hello and asks us to do some tests on him to confirm it.

It seems that in each of these cases it ceases to be philosophy and becomes another science. Agree? In general philosophy seems to be is about constructing consistent world views - like utilitarianism or nihilism (ethics makes a good example for that but it carries over to other feilds).
