"is there really anything considered as God (s)?"
Yes there is. Really.Is there really only the universe we live in? No. There are gods, dreamtimes, walhallas, quarks, leptons, curved spacetimes, Calabi-Yau manifolds, nirvana, witches, shamans, ghosts, vampires, dadaist programmes, field fluctuations and virtual particles, art, poetry, photographs, a zillion languages (though that number is decreasing rapidly to be taken over by English and math, the allegded native tongue of Nature), Bessel functions, hidden variables, untrue Higgs mechanisms, rishons, lies and deceptions, Tavistock manufactured shocks, deliriums, drugs, visions, dreams, jealousy, parables, allegories, computers, quantum fields of gold, musical trance, false flags and black ops, conspiracies, trains of thoughts, solitude, moonlight drives, strange little girls, Siouxies, Aboriginals, Hopi (though less and less, psychoses (maybe drug induced), euphoria, fears, mosques, temples, proofs, etceteras, and many more. If that is no proof of god, I don't know what is. What is a proof of god? An actual encounter? Who would believe you? Mozes spoke to him. Received messages. There were even mass revelations. But normally they don't show themselves. Especially in these days. They showed themselves to the old Greek untill the One-entity, this monster of Xenphanes replaced them. Still around today...
