To be honest, that's not what I always hear.
I think there are some good reasons to believe, besides "you must".
That's the simple answer that a bored adult gives to a child.
But the reality is that there is logic to religion. I don't think it's true, but I don't think that the only reason to believe in a religion is "you must". I just know there's more to it. A desire to know the universe and why it exists and why we are here. Don't you think so too?
I agree 100 percent with you, prophet Adam. P.B.U.H, also question all that u mentioned, at his time must where idol worshippers, and that's what God says if u don't worship, me I point others for u to worship. Take a look around u now, must people are either, idol worshippers, e.g jazz Beyoncé and so on, and others worship money and sucess, I think u get where I'm going with this.
Sorry my bad not prophet Adam it's Prophet IBRAHIM
