By simple analogy. You can prove that there are white crows by finding a single white crow, but to prove that there are no white crows you must conduct an exhaustive search of every corner of the earth and never find a single one and somehow be absolutely certain that you didn’t miss one somewhere.
The only way to be absolutely certain that you didn’t miss something is to be able to look everywhere all at once, otherwise a white crow might evade your notice, and that’s impossible.
As such all you can say is there probably aren’t any white crows because we have lots of experience seeing crows and there has been no evidence of one yet.

This is a very good analogy!
Although to be pedantic, there are white crows; there was one living in my neighborhood some years back.
