Due to the huge number of religions and varieties of God, sooner or later a person will have doubts about his existence. I think the universe itself can control all beings.
agree all about rules and fact (reaction)
Yes, there will come a time that all of the people will be confused about who they will worship due to the out growing number of religions. Some will doubt their faith to God because of the other gods that the other religion introduces to us knowing that there is only One God but many or different beliefs and principle of many people with regards to religion. But for me the bottom line is that we should respect everyone who has a different principle about God and religion.
