the point is i have a reason to have a belief in reality.... its called rationality or being forced to deal with your experience. reality cant be proven, but there are reasons to believe its true.... this is why we have (burden of proof) or reasoning, like in a courst system can u prove the man didnt commit the murder, not the right question, its impossible to prove someone didnt do something. the right question is can we prove the man did commit the murder.... the onus is on the the person making the truth claim , not the other way around...
