Religion confusions

[Vegan atheist]

Hello everbody so I use to be a Muslim and I currently don't believe in Islam for reasons bt something has been making me confused in the past at Ramadan time like 12 years ago there,s this time at the end of Ramadan Muslims call alkadir which is like if you keep on watching the sky throughout the night you'll something different from Allah my family saw this big lightening hole in the sky at the alkadir days they were shocked now I would like to know is there any reasonable explanation to this and why did it happen specially in those days? And also islam preaches against alcohol they say because it could ruin your life bt I see that if you drink too much it,s your own will it,s like the bottle forced you to drink it and also they preach against things that have some reasons to them bt I don't believe in Islam or don't follow it because it has so many horrible acts please if you can explain to me why all of this stuff is crap thank you very much
