This is the old debate. Everything you experience is God, because it is connected and everything, and these are the properties of God.
Still, experiencing something doesn't count as evidence that it exists, as people can be deluded.
Many people have directly experienced talking to extraterrestrials, or some divine beings, in near-death-experiences, or in dreams, yet it doesn't count as a piece of evidence that these experiences have been real.
It's been alluded to in Don Quixote in the scene when Sancho Panza descended into a deep cave and had been wondering thruout the rest of the novel whether the experience was real.
If seeing God or Jesus directly is not a proof that these entities exist (and I do not claim it is), then neither is seeing your mother, myself, this article, your own reflection, your teacher etc.
None of these experiences prove that any of these is real.
All you can do is have these experiences and try to learn from them. You will have to either find a way of distinguishing which experiences are real and which aren't, or agree that you will never find a way of knowing that.
Actually these are the conclusions I've came across while studying spirituality. These views have been addressed by Thomas Campbell in their book 'My Big TOE', and even by Elon Musk in some of YouTube videos.
You cannot prove whether even you exist, so why would you try to prove whether God exists? Deal with it.
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
