mhen , u woulda practised ur childhood religion cos it would help  u to know how to differentiate from that and the other ones. Now u dont have a practical background of any religion , its gonna b tough. in my opinion, i think u can search the religons n find one that is most peaceful or the one u feel most comfortable with. I assure u if u wanna go into details to get into one religion , u'd never b satisfied with the answer. I have a religion i practise , but damn religions r complicated issues. Pray to "God", just call him "God " n i believe d right one will def. answer.
