If you say so
I don't know off the top of my head. But by looking at different things around the house and internet I can gather enough evidence to give you an answer. Which is exactly how scientists use evidence to discover things in the past.
No. In your life you never present evidence like that to tell others what you did. Others will not demand your evidence to get to the truth. They rely on faith in you to accept what you said about what you did.
That's the reality you are living!
Only in specific scenarios that a difference than this will be made. Science happens to be one of these scenarios.
Moreover, human history as a category of truth is mostly unsupported by evidence. History is basically a mixture of human witnessing. You need faith or no truth can be presented.
That's the reality you are living!
