funny as you state it, someone's own belief doesn't stand as a proof of existence, your simple belief or experience of thousands of people among the billions doesn't count as proof. Some people may experience Allah, some may experience Rama, some even have faith in Flying Sphaggeti monster..if everytime people's faith and beliefs started to count as evidence, then well someone claiming superman to be real can't be countered as it is his own belief, just because you want something to be real or believe that it is doesn't make it real, it's your own opinion. Thousands of years ago, greeks experienced Zeus, egyptians experienced Amun Ra,but look at that now, they are simply debunked as myths, that's what it really is, when the majority starts shifting to one side of the debate automatically the other is argued as being fake, so to be frank i can't prove God's inexistence but neither can you prove his existence. Arguing that maybe i am unreal, funny atleast i exist, but God somehow doesn't seem to
