Atheists,you demand evidence,do you think prophet mohammad got to see Gabriel for free?

since childhood till his 40s,he had a theory at first which says that the universe must be created by the right and justice,and he saw the way people living as wrong,(cheating,lying,showing off,arrogance,racism,crimes,greed, adultery,gambling,decieving,etc) and there must be a straighter path out,and then after he insisted this theory although he had no evidence yet but just because he was so partial to the right and justice and he had no hesitation and no way back to give up that belief then at that point when he is already believes that right and justice is the way to be he deserved then to see the evidence so Gabriel appeared to him as a massive personal and execlusive evidence to tell him that he is right,and his theory is not a theory anymore now but a certainity,and thats what people are tested about,so why he is the only one who saw gabriel? its because he believed the most in virtues,right,justice more than any one else,so he deserved to see the biggest signs,he even saw bigger signs than Gabriel in the journey to heavens,surah 53:18,,so everyone gets to see as big signs as much as he is partial to these principles (justice,rights,etc),and I realy find it working to me this way and I found a supporting evidence for this policy in quran in surah 29:69,now im getting my faith boosted every when I do good behaviours and insist that universe was made by right and justice so I perform right and justice.....its just not fair if someone else gets to see the big signs if he didnt do good enough to see it because its a test and its up to how good everyone is doing,so if other people saw the same signs prophet mohammad saw then they will have as much faith as him while they didnt work hard enough for it,he just deserved to see his signs,its not a test anymore if you see then believe,this invalidates the test which based on right and justice that you should practice without demanding evidence,then when you already good God will show you signs,surah 29:69 and surah 8:23.
