Disagree. My beliefs are commensurate with the quality and quantity of available relevant evidence. And it's not as simple as accepting a belief or rejecting it. For the critical thinker, belief is never 100% certain. There is always at least philosophical doubt even if there is no feeling of uncertainty, and belief in ideas about how the world works are semiquantitative ranging in degrees of possibility from possible but unlikely possible but likely to very likely to so likely that it would be unreasonable to seriously doubt the idea beyond philosophical doubt. Furthermore, such empirically justified beliefs are amenable to increases and decreases in the degree of belief pending the discovery of new evidence that makes them more or less likely to be correct.
I still disagree. I don't think you or anybody else can name an example of a belief that I hold that is not empirically (experientially) justified. I can't. I'm pretty experienced in critical thinking, and do it as automatically as saying please and thank you or looking both ways before crossing whenever confronted by a claim, and all for the same reason: they are cultivated habits of thought that eventually define behavior wherever applicable.
Prove it to whom? Myself? You? And you know the problem with the word proof, which I am modifying to convincing demonstration.
I don't think I'm going to be able to explain this to you. It seems like you don't know what empiricism is. In a nutshell, it is the application of reason and one's fund of accumulated knowledge to the present evidence of the sense, which then increases one's fund of accumulated knowledge. How do I know that I made a suggestion? Use your eyes. Here's the suggestion. I made it. Therefore, I have demonstrated that I made that suggestion. Here's a screenshot of it:

What do you think the likelihood is that I DIDN'T make that suggestion given the evidence before your senses now and your understanding of what it likely signifies? In your position, I would go with "very likely." It's more than just possible or even likely, but it is not beyond reasonable doubt that somebody else wrote it using my RF account or that you modified it besides just changing the font size of the first two words.
And I see that you ignored the suggestion. How do I know that? Empiricism. The evidence of my senses properly understood. I see my suggestion and your evasion of it with the above deflection.
