Brother you need some strong evidence or proof to believe in Allah the way you want to??? Do you even know what Iman is we are talking about? To believe in unseen, untouched, unheard. which means you will believe in what your Nafs has never check up on. And to believe once you discover or been confirmed about the matter, comes under the definition of Witness and not Iman. yes Mohammad s.a.w and Quran are the witness there for us, but you were not suppose to recite the verses to judge and doubt them and compare then with human researches and studies. Many of the scientific advances were been proposed, appreciated and approved in one period while rejected in next with more experiences and acknowledgement. you should doubt these human, -----ists failure,have not reached to discover the truth. They are in progress, you may say, in various fields. btw who is going to give you the proof about the existence of Hell or heaven? the Jin or the spirits? the Jibril and the sahaba? so it means you will not believe in them? when Hadrat Ali r.z (a child when has) accepted Islam did he r.z asked for some solid proofs? Just STOP asking for evidences, do wudu, say Two rakat salah hajaat and don't delay brother, ask Allah for help. and then Think who can be my creator? can the Name ALLAH be a fake one? can Surah Rahman be a human work? subhanAllah. you will start believing Allah. If your Nafs/satan insists you to provide evidences then just neglect them. may Allah help you out and save us from such evil whispers.ameen.
