i personally dont believe, in religion. Simply because it doesnt help me, the thought of a 'god' jut doesnt impress me or anything. it kinda makes me feel like i have a constant parent that you must obey or get scolded, and for me personally (when i'm not suicidal) that is not what life is about. yes treat others with respect and how you would like to be treated, but to me thats not what a religion should teach, thats just basic decency. as for heaven hell etc. no one knows whats after life. biologically speaking, theres nothing. spiritually speaking, whos to say we have a spirit? other than belief there is no proof of a spirit. thats (for me) just a comfort for people who maybe afraid of death, which is understandable, but no matter how you go, everyone will die. wether or not theres a heaven, hell, god or devil.
just my opinion.
